BMW i8's produced in the EU from 1/3/2018 to present have a petrol particulate filter inside the muffler. Feedback from owners of EU produced BMW i8's report very little difference in exhaust note when modifying the exhaust in these cars. Be aware, if your car was produced from 1/3/2018 to present, any exhaust modification may not produce noticeable results, as the particulate filter installed inside the muffler, may be restricting exhaust noise from reaching the tail pipe, regardless if the exhaust flap is open or closed. Thank you to Fred Halvorsrød for performing the testing, research and feedback on this topic.
I spent many weeks trying to figure out how to modify my BMW i8 exhaust. The exhaust valve is electronically actuated, and normally closed. So, I needed to figure out a way to open it and then keep it open. At first, I disconnected the actuator from the exhaust flap and wired it in place. That worked well, but I wanted a less intrusive way to keep that flap open. So, I spent time researching the BMW i8 service manual and discovered that the exhaust valve actuator was protected by a 7.5 amp fuse labeled Fuse 58. I disconnected the fuse while the flap was closed and the car never displayed a trouble code or check engine light. This was good data, as I was able to determine that pulling the fuse would not result in any annoying notifications. However, in order to keep that flap open, I would need to drive with the engine under high load (in Sport Mode at Full Throttle). I decided to try to pull the fuse by myself while operating the vehicle. What I decided on was to use a string and a 10lb weight.

I let my wife punch it while I was upside down in the passenger seat at the fuse box.
Nailed it 😂. Thank you Pat
You are a superhero!
Very creative! Quality content ... like modifications that can be reversed and leave no trace. Thanks.
I love that you linked the weight and the string! 😂
Now just waiting for you to figure out how to get our 3 cylinder to 600hp like the Koenigsegg Gemera.. Lol
Let's see. Remove the cam and replace it with electronic valve actuators, run it on E85 fuel and increase the displacement to 2.0L. Let me get my drill... 😂
@@PatsGarageOnline hahaha
@@PatsGarageOnline And since I work at Koenigsegg, I can see if it is possible to do a swap haha
Let's do it!
The gemera has 3 electric engines and a 3cl 2.0l petrol engine. The i8 has 1 electric engine and a 3cl 1.5l Petrol engine. You can’t have 600hp on a i8 but you can reach 400hp easily with a stage1 remap
Great vid, I may have to try it when I get my i8 back. I would think with my luck, it would be revealed that I was excited for nothing cause I was only hearing the exhaust "audio" produced by the speakers :/
Open the valve with almost any diagnostic tool and remove the fuse simple as that :D
@@fodordaniel9659 I did a separate video doing just that.
Your channel is awesome Pat. I wish I found this soon, I could've save a lot of money haha. I drive a 2016 BMW i8 and these clips are very informative. Meep up the great work.
Thank you! It's my goal to figure out ways to enjoy my i8 on the cheap. I'm glad the videos are helpful.
Well I'll confirm the roadster is slightly different
I looked at my fuse area there and it's already gone. I have used bimmer link to open the flap you can hear it open while not driving but you do have to open it everytime you turn on the car
Please keep up the good work and I wish you get more likes and views..your contents are very clear and informative
This is really smart! This is the first mod I'm gonna do whenever I get my i8.
Now that is a brilliantly simple plan. Really brilliant.
Sorry double post in the previous video and here: I do not recommend removing it or leave it open. The exhaust valve needs to control the outlet airflow, so it can be more efficient. When the car is low speed (closed = good for a rev up), high speed (open= better for high speed)
Blocking the exhaust will slow the turbo down.
@@7invi please Google back pressure on a turbo engine
@@PatsGarageOnline Ok ( I removed the fluid piping's comment) , as you said I did google again, and the results are below:
"Back Pressure"
Do you need back pressure in an exhaust?
As the pulses move along, they generate an exhaust flow. If you have a restrictive exhaust system, it can cause backpressure that works against the positive flow of the exhaust gas that's trying to exit your vehicle. ... However, a little back pressure is a good thing. In fact, it helps.
"Exhaust Gas Flap Functions"
In emission control, exhaust gas flaps are used to divert the exhaust gas flow. In this way, they trigger the HC (Hydrocarbon) absorbers or bring the starter catalyst to operating temperature more quickly.
A more recent method of emission control is the use of DeNOx catalytic converters. These cause a part of the exhaust gas flow to be guided through a cooling zone by an exhaust gas flap, thus ensuring an optimum effect and a long service life of this catalyst.
By varying the exhaust gas backpressure, the efficiency can be improved in certain characteristic areas. This is also done via an exhaust gas flap in the exhaust system.
Exhaust gas flaps are specifically dimensioned to meet the high demands in the exhaust gas system: they must outlast gas temperatures of up to 950°C, whilst closing correctly and remaining moveable during their entire service life.
@@7invi I challenge you to dig deeper: Impact of Back Pressure On Turbo
I love your channel, been saving so far for a year. 1 more year & I can purchase one. I am going for a 2019. I've been told all the problems that it mainly comes with & what needed to be changed to make it better. Has been done for the 2019 model.
Thank you! Don't believe everything you hear. There weren't that many issues with the early ones compared to the late ones. That's what I've been reading on the forums. In addition, a lot of parts have not been deprecated. So buying a newer one versus an older one doesn't mean you're going to avoid any particular issues. In fact, the 2019s and later seem to have a problem with the trunk lid pivot and spring breaking more than the early ones.
@@PatsGarageOnline Much appreciated for letting me know, information is power & I appreciate the feedback. I will opt for a 2014 or 15 then. Save the extra money left over for repairs.
Thanks Pat! Cant wait to try this. Will prob do tbis before I use a real weight for exercise!
Gonna do this myself 😄 Thanks for the video
Nice to see that you've pierced through the 800 subscriber mark Pat. Save the Wave.🙋🏼♂️
Thanks 👍
Hi Pat. I have completed this mod and to be honest haven't noticed any difference in sound whilst driving the car but used a decibel meter and have noticed a very slight 2-3DB increase at the tailpipe whilst idling. However the one difference I have noticed is that my oil service mileage indicator is reducing a lot faster now that the fuse is out with the flap is open. Before I carried out this mod, after my oil service indicator went under 1000 miles, whatever mileage I covered with the engine running would correspond exactly with the oil service indicator. Basically like for like, if I drove 40 miles with engine running the oil service indicator would reduce by 40 miles. Since I have carried out this mod it now drops dramatically with each journey using the engine. For example it dropped from 430 to 370, a 60 mile drop when I had only driven 15 miles. Basically each time I drive using the engine now the mileage drop is no longer like for like and instead it drops by 60 miles each 15 mile trip I take to work using the engine.
Have you noticed a similar scenario since carrying out this mod?
I know the oil service indicator depends on numerous factors and calculations depending on how the car has been driven and how the hybrid powertrain has been utilised between services. Is it possible that this actuator controlling the flap was part of the calculation and now that it is permanently open the oil service indicator thinks my car is being driven at full throttle all the time, subsequently reducing the mileage in-between oil services?
Love your videos about the i8 by the way and plan on carrying out the air box mod this weekend.
Cheers Ryan
Thanks Ryan. That's interesting that you can't tell much if a difference. We're you able to look into the exhaust pipe and see the flap open, just like in my video? A couple of folks reached out to me and sent picture to my Instagram at @i8.pat so I could review them. One subscriber only had the valve half open and needed to try it again. I want to make sure yours is truly completely open.
I was unaware of any changes in oil life in my i8, but I don't watch the meter. I change the oil every 5k miles. A turbo, direct fuel injection engine goes under a lot of stress. Fresh oil is important to me.
I'll have to start watching the meter when the world opens back up. I haven't been driving the i8. I've been doing paint correction and other things. But I'll take a look if I start driving it again.
Please let me know if the flap is truly all the way open. Thanks!
Hi Pat. I'm pretty confident the flap is open. I did multiple tests with the flap closed and open when I was testing with the decibel meter. I soon established that if I didn't pull the fuse out when I was on full throttle the flap would only remain partially open. On one particular attempt after pulling the fuse out the flap only remained partially open and ended up making a hell of a rattling noise because the passing exhaust fumes were obviously causing the flap to rattle against the side of the tailpipe or something. There's another easy way to test if the flap is open by simply sticking my fingers up the tailpipe!!!! When the flap is closed you only feel heat and exhaust gas pressure from the left side tailpipe and with the flap open you get the same amount of heat and pressure out of both pipes. When I'm carrying out the air box mod this weekend I'll get a better view with the car jacked up and send you a picture. You never know maybe once the air box mod is done it will bring the exhaust mod to life. I watched your video when you were driving and listening to the noise after you had made the mod and I never heard any difference to what my car sounded like without this mod. I've always heard the engine and exhaust noise in Eco and Comfort modes with "hold state of charge" deployed.
Believe me I don't normally drive about keeping a constant eye on the oil service indicator but when you get under a 1000 miles to go a message pops up on the dash alerting you each time you start the car. I fall into the "key worker" category over here so have still been using my car for work and have been trying to drive as much as possible in full electric mode to save the oil life which is doing my head in. 30 mile round trip today, 19 of which in electric mode and the oil service indicator dropped from 310 to 250. It's like playing a game with it or like waiting for a time bomb to go off and really annoying especially when the car was booked in for this service at the end of March but got cancelled due to the lockdown. So that's how I've become so aware of the difference ever since I did this mod. I'm not saying it's definitely due to the flap being open but seems very coincidental.
I'd love to change the oil more frequently but have an extended warranty with my 2014 i8 and find it costly enough having to pay BMW's extortionate prices to do so in order to keep my warranty valid. I can't even fit the wider tyres like you have done and just have to put up with the understeer. I enquired about it but it would have voided my car insurance in the UK as well as the extended warranty. When my extended warranty runs out I'll grow a set of balls and invest in a decent set of tools and carry out all the service requirements! Maybe that's wishful thinking due to how easy your videos make it look.
@@ryansteel7189 Thanks for the detailed reply. I can confidently say you went through the checks to make sure it was open, especially if you heard the rattling noise. That doesn't always happen in a half-open flap but it's more likely that it will because there is less pressure between the actuator and the flap, mid-travel. Sometimes, I get questions from folks who aren't as knowledgeable as you. But you are clearly ahead of the game on this, so I trust your judgement that the flap is indeed open.
I wasn't aware you were in the UK. Does your exhaust have a Particulate Filter on it? In the US, we do not, and I honestly don't even know what it looks like, but if it's there, I wonder if it's helping silence the exhaust.
It makes sense, now, why the oil life is something you are concerned about. I would advise putting the fuse back in the panel at this point, in order to rule out any variables with regard to oil life. From my knowledge, the car will adjust the oil life based on driving and performance. BMW claims that 10,000 miles is the required distance to change the oil, but we don't know what the modules are programmed to alert, since the combined gas/electric use will result in completely different miles (for example, 2,000 miles / 8,000 miles gas may not require an oil change). We (the consumer) are not aware of the actual mileage on the gas engine. That makes it difficult for me to know exactly what's happening. If you are that close to an oil change, it's possible that the car is more sensitive and/or the flap might actually have something to do with that. It might be in your best interest to re-install the fuse so you don't run over your oil change limit, because I'm very unsure if that may have an impact on it.
Apologies for my late reply Pat. Since I reinstated the fuse I have been trying to establish if the flap being permanently open has any impact with the mileage of the oil service idicator. The mileage of the oil service indicator seems to be a bit better and like for like with whatever mileage I have driven. However I have been driving in e drive mode only to save the life of the oil, so it's hard to say if the flap being open has anything to do with it or like you say just more sensitive as the service mileage indicator reduces. Maybe once I get the oil changed I'll try again with the fuse in and out.
I don't have a clue if the Uk models exhaust has a particulate filter on it or not. I would normally ask the techs at BMW but they have all been furloughed due to the lockdown but will endeavour to find out now that you have mentioned it. Even if it does have it, I doubt I would be able to remove due to MOT emission test parameters in Scotland.
On a separate note, just wondered if you ever developed a solution for the shock absorber dust covers (protective tubes) that had torn?
I have the same issue on both rear struts and don't fancy having to pay BMW £4k to replace them especially if they are going to be made of the same flimsy material so would like to find an alternative solution.
Very interesting video that reminds me of a similar modification that I did to my Jeep Wrangler.
There is a fuse that protects the interior lights and needs to be pulled if the doors are removed. I replaced the fuse with a dummy that had two wires coming off which I connected together via an inline fuse and a switch. The circuit is still fused but now, when I remove the doors, I just flick the switch to stop the interior lights staying on.
I guess the same thing could be done to the i8
Yes, the same can be done with the i8. I didn't get into that in the video because of liability concerns. But, that would be the most functional way to make this happen.
@@PatsGarageOnline Makes sense - there is a world of difference between modifying a 14yr old Jeep and a BMW i8 :-)
WHY would it be soooo hard to tap into where the fuse goes, and put some long cable and a switch some where by the drivers side, hiden away under the dash, that way you can have exhaust fully open all the time when you switch it off and fully stock when you have it turned on. I done this myself with many fuse aplications.
I did it after I created this video but never recorded a follow up video. It worked well.
@@PatsGarageOnline seems the most logical way to have it done. But we'll, that's past, you sold the car anyways 👌👌👌👌😏😏😏😏😏
What your experiencing is the placebo effect, just like fake muffler they put on to fake exhaust note, at lower rpm, the exhaust exit out the left pipe, at higher rpm, with greater volume of air the flap open for efficiency, so the flap normally open at or close to wide open throttle you didn’t change a thing. You just proof that the 10lbs weight is more than enough to pull a fuse out under the glove box
Try the mod on your i8 and let me know what you hear
@@PatsGarageOnline here is my mods, you can find it on Craigslist, for sale 2017 BMW i8 Lamborghini trade welcomes
Use BIMMERLINK ( sister App to BIMMERCODE) to open the valve , then switch engine off and pull fuse. The good thing with BIMMERLINK is you can try the exhaust open to see if you like it before pulling fuse.
Very good advice for iOS users. 😁
Did this mod today .... Great mod ..sounds much more like a sports car ...deep burble ... well done Pat!!!
@@tube1923 bimmerlink doesnt support i8 valve open
A great & simple mod.
Could you not wire a dash mounted switch in place of the fuse so you can have the option either/or?
You could mount a switch. that way you can open the circuit when your foot is to the floor to prevent the valve from closing. I decided not to get into this since it requires some custom work and it didn't want to take on any liability in the video. But other vehicle owners who have similar vehicles have decided to install some type of switch in order to break the circuit.
to be safe with insurance (maybe is usefull) put in back a blowed fuse :-)
and btw ..you can use the dumbell now again - is good for you - no need to let it in the corner ;-) stay happy/lucky/healty
y un interruptor, ?
ponerle a la base donde va el fusible una extension,con interruptor?
on off, cuando se quiera
Hi Pat you should really watch my video on the changing your wheels for the I8 makes the car look a 100 times better
Subscribed! Congrats on the i8 purchase and welcome to the club! Please consider joining the FB i8 group and sharing your video. facebook.com/groups/bmwi8group/
When it comes to wheels, I'm an outlier. I actually like the stock Turbine style rims. My car came with the W style rims and I found the Turbine rims, used, on eBay and absolutely love them. Edo Popken is running EM OZ forged 20” wheels with Michelin Cup2 245 front 265 rear for the least unsprung weight he can on the i8 ProCar race car in Germany. But, I'm not really concerned about weight.
Hi Pat,
I've just carried out this fuse removal BUT to fix a squeak that I thought might have been coming from the fall. Turns out it was as squeak is gone! Question is if I put the fuse back in what would I need to do to fix the sqeak? Where would I lubricate it do you think, and how? Cheers Chris
There is a hinge on the valve that you can see near the end of the tail pipe. The hinge could be corroded causing the squeak. But I wouldn't squirt anything flammable on that.
@@PatsGarageOnline Thanks - white lithium grease when the pipe is cold?
@@user-rz5co5qg6e that's your call. I would personally start with soap and water to get the soot out of it. That may be enough.
Hello if you don’t mind can you give me the idea my i8 has issued with control screen on the console no light and can’t click or move to anything on the screen after you did changed the new 12v battery
I would try disconnecting the 12v battery again and reconnect. If that doesn't work, visit a service center
Thank you so much
Thanks Pat!!
great info as ever
My 2006 Aston Martin had a valve and I removed the fuse and it stayed open, :p
Thanks Pat, again well explained video. I have an 2015 i8 and love it. My biggest complaint is lack of noise! So, if I remove the fuse 58 permanently, will that valve stay open permanently and get that noise that I am seeking? Do I need to be driving and then remove the fuse? Sorry for the confusion, just want to get it right. Again, Pat thanks so much.
Thank you. Yes, you need to be driving and have your foot to the floor in order to put load on the engine. That opens the exhaust valve so then you can pull the fuse while the valve is open. This requires either two people or one if you use some type of device like I did in this video. Once you get the exhaust valve to stay open, Just leave the fuse disconnected. The other option is to plug the fuse back in at any time, and it will go back to operating just like it did from the factory.
@@PatsGarageOnline Pat, I followed your advice and worked perfectly. Kind of cool - getting more sound even al low RPM. Again, thanks and keep posting!
Hey pat is fuse 58 the same fuse for a 2019 bmw i8 I don’t want to ruin my baby if I do this hack
I just pulled up the service info on the 2019-2020 cars and the same fuse 58 is used to control the exhaust flap.
@@PatsGarageOnline your one of the best CZcamsrrs appreciate all you do! Will be doing that tune soon and using your 50 off promo code thanks brother🙏🏻.
should I pull the fuse 58 before I tune the i8 or after I tune it so I don’t get that check engine light ??? What do you recommend
Hi Pat, another great vid. Where would be the best place to ask you a question about the i8 that is not related specifically to this video?
Actually am just going to ask it here. I’m just over a year into my i8 ownership and wonder if you have the same problems I do with the seatbelt guides (on the sides of the front seats)? Both myself and passengers have this issue, the belt never stays within its guide meaning when you put it on you have to reach way back to get it. These seem poorly designed to me - I know they probably left the tops of the guides open so that the seatbelts wouldn’t always obstruct access to the back seats but how often do you have passengers back there anyway? Whenever I take my sealbelt off it never stays inside the guide, maybe because my shoulder level when sitting is higher than the top of it possibly, though I haven’t fully analysed this. Do you have any suggestions or perhaps even a robust solution/mod for this issue by any chance? (hint hint ;)
Thanks for asking here. It's super easy to reply.
I suggest that when you take the belt off you lay the belt inside the seat bolster. That means that your back will touch the seat belt. If you do this every time, the belt won't flop outside of the seatbelt guide and it also gives a neat and clean appearance when leaving the car.
Thanks, why didn’t I think of that? Will definitely try this next time!
Can you do a step by step idiots guide to this pls?
It would be a cleaner mod to just just build a switch that replaces the fuse and hide the lines for a clean install.
I actually did this last week. Works well.
Very interesting vid bud!
can i just rev it to 6-7k rpm and pull the fuse?
And welcome to Pat's Garage, where you will not only learn how to modify your exhaust, but you will also develop an 18" bicep.💪 😉
Pat, did you take a page out of a comparable hack for the C6 generation's dual-mode exhaust? "Normal" operation was for them to be closed until about 3k to 3.5k rpm at which time they would automatically open. The only way to make them stay open all the time was to pull the fuse, which you did not have lto do ike what you did. You could take the fuse out even with the car turned off. FWIW, I know the C7's can override the "normally" closed valves electronically. Newer generation, newer and improved technology for sure.
I would have preferred you used the Lady Becca over a ten pound weight though.You could have injured your Rotator Cuff! 😊 It was brilliant hack Pat! You do bring new meaning to the maxim that "There's more than one way to skin a cat." 🤣 Save the Wave.🙋🏼♂️
Thanks Peter! Lady Becca has been spending all of her free time at the horse farm, prepping her horse for sale, so I'm on my own most of the time. So, I had plenty of time to figure out how I was going to test this. Unfortunately, the i8 requires the engine to be under load (according to the technical training manual), so I can't just rev it and pull the fuse, I have to drive it. I wasn't aware that the C6 also could be modified by pulling a fuse until you mentioned it. But, speaking of a rotator cuff injury, I have it. I fell asleep weirdly Wed night and I knew it, but didn't roll around. In the morning, I woke up with pain in the shoulder and it's still here. I'm on "light duty" right now, hoping for some relief, so I'm taking it easy...
@@PatsGarageOnline As always, thank you so much for your reply. I forgot about Lady Becca's love of and responsibility to her horses.
I did mention the Rotator Cuff in jest, but not entirely. I really injured mine while doing dips on the parallel bars. This was confirmed through an MRI that I had torn it and I was in lot of pain. Surgery had been scheduled, which I had to cancel at the very last minute due to family emergency. Anyway, with a lot of use of Advil and a great Sports Medicine MD, I came back. Well, I "came back" more in my strength than in my flexibility. But at least I was able to remove my pull-over shirts, which I previously was not able to do. I was also no longer able to throw a fast ball or a long pass, but who am I kidding, my glory days are long gone. I'll take a shirt removal any time and I don't mind be a Water Boy for the team. I can still hold my own with them in gym, as long as I stay away from the parallel bars.😁 As you stated, stay on "light duty" and eventually you'll do well.
Save the Wave, even if only half a wave.
Thanks Peter. Sorry to hear about all the issues you've had with your shoulder. I've been very lucky not to have something like that happen. This is just a freak situation of sleeping the wrong way leading to this problem. I feel it more when I call or wash my back with that arm. I'm able to get my shirts on and off with only a little bit of pain. Nothing to the extent you went through. So I probably just strained mine. I'll be sure to take it easy for a while. Thank you.
Thanks Pat. And if by some chance you think it's time to push the envelope during your period of light duty, call me. I'll come straight down to Maryland with two bottles of Johnnie Walker. One Black Label and one Gold Label. By the time we knock those two puppies back, the only range of motion you'll be concerned with is if you can still lift a glass to down more of the Nectar from the Gods. Don't worry, if you find yourself tightening up, I'll bring straws, loooong straws. Zero range of motion required. No, no, no, don't thank me. That's what friends do when friends are in need.🤣 Stay strong 💪my friend. Don't worry, be a happy. Hey, I think I may have to make up a song about that.😁
I'll take it. In fact, I'll gladly share my JW Blue with you (only served for special occasions with good friends). 😉
Good job 👍👏
Been watching your videos for about a week and my question to you is. Do you know anybody having a problems with the new BMW I8 2020 because I see you are doing reviews on your BMW i8 which is a 2015
Problems seem to come about with age. The 2014/2015 models are showing issues that the 2016s are starting to develop. So it may be a few years until we see these problems on the newest i8s
Hi Pat does remove this fuse 58 with the open exhaust valve opening.....Does this have an effect on the MPG?
There is no change of MPG
Does the i8 have a rear jack point where I can lift both rear tires? I'm trying to put my i8 on 4 jack stands so I can remove the wheels to get it powdercoated
Hi Wendy. It doesn't have designated jack points outside of those plastic ones just under the rocker panels. However, the lower rear controls arms bolt to a very large aluminum sub frame. You just can't see it because the aluminum cover is installed under the car for good aero. But, I was able to put a jackstand on that area after I jacked the car on the plastic jack pad. I did this in this video: czcams.com/video/xp0KdLzJwho/video.html
Rich Rebuilds is pointing to that area, here:
czcams.com/video/TP8IAsPyJ58/video.html
It's not something BMW would likely recommend, and I can't advise to protect myself against liability, but if you did decided to try jacking or using a jack stand on this area, you might consider putting something like a hockey puck between the jackstand and the vehicle to prevent marring.
@@PatsGarageOnline gotcha. Thanks for the info.
Hey Pat does this allow you to “rev” the car?, meaning it’ll be as loud as in sports mode
After doing the exhaust mod, it sounds like Sport Mode. You can rev the car If you get in the car, shut the door, put the seat belt on, put your foot on the brake and hit the start/stop button, then put your foot on the gas. That'll cause the engine to start and then you can rev it.
On a late production 2018/19 can you just remove the fuse when engine on or off Pat.
Even in late model i8's, the valve us closed until you demand high power from the engine, according to the technical training manual.
Anyone has check engine light come on and off after removing the fuse? I would have check engine light up for a day or so and then dissapear for a week and then it would come back again on my 2016 i8. The fault code is exhaust flap.... i put the fuse back in and 3 months now - no check engine light anymore.
Hi Pat, do you know how to increase the engine sound coming from the speakers, inside the car? Thanks!
Unfortunately, that's not possible. The internal sounds that augment the engine noise are integrated into the sound system and can't be altered. The small speaker at the back of the car won't generate engine noises below $3,000 RPM. There are aftermarket options like Maxhaust but this does not sink well with the exhaust note coming from the car.
@@PatsGarageOnline thank you so much Pat! ... even if I was really hoping there was a solution for that...
Hey pat when you turn on the car will it have a cold start or is it still quiet ?
The car starts in electric mode. If you wait several weeks before running the mid engine, the mid engine will also start in order to keep the oil circulating.
Before I commit the time, what's the value of keeping it open?
The advantage that I noticed is sound. Me and my passenger thought there was also an increase in power from the seat of the pants but I cannot confirm nor deny it. It just felt different.
Hi Pat, Have you ever considered a reflash and tune?
Not yet. I'm concerned about warranty and cost.
Pat's Garage Online This is my daily so I’m not wanting to compromise it’s rather wonderful balance of performance, economic functionality and overall usability. Also, the available tunes are
question is it possible to put a better turbo in it to make at least 100 more hp
Check out Edo Motorsport on Facebook. He developed a turbo and intercooler for the i8 ProCar that he is bringing to market. He is in the EU so we would have to pay duty in the states.
Pat's Garage Online I’m thinking of getting a i8 in the near so your videos been helpful
Pat, how can you reverse this modification in the event you want to go back to quiet mode on low speeds
Simply re-insert the fuse back into the fuse panel. The car will determine the correct position for the flap as long as it has power.
@@PatsGarageOnline Awesome... I have 2017 i8 Frozen Protonic Black edition and it is so much fun to drive it around...I love your insight and am always looking forward to next video.. 🙏
My don't you install a x Fi exhaust on your BMW i8
The aftermarket exhausts out there seem to make the car sound more like a diesel engine or a lawn mower. I honestly don't find that appealing in an expensive sports car. But, if other people enjoy it, that's great. It is truly a matter of personal preference. 😀
Hey pat I'm looking for your videos
Hi pat, is there any way to increase horsepower ?
Several i8 owners have installed the Vivid Racing tune found online or other tunes. The 40 or so HO I'd get for $1500 isn't worth it to me, however. Edo Motorsport is working on developing a new turbo which will definitely help.
Pat's Garage Online great thank you pat 👍🏼
Could have just used Carly to code the flap open and then pull the fuse out...
True. I didn't want to purchase Carly, so I figured I'd give this a try, but Carly will work.
Pat's Garage Online your videos are so helpful, I’m looking to get an i8 in the near future and all of your videos have helped me look for certain things and have allowed me to be able to see what it might be like to live with. Quick question though, your dyno day video confused me a bit because of the numbers the car made. So how much performance increase was achieved in the end?
The car gained a few HP and Torque numbers but my 0-60 testing proved a lot to me as I don't care as much about the dyno numbers than I do the seat of the pants feel I get driving the car. Most people don't care about "a Prius" like I own so I really can't talk smack.
Cool mod but if I had an i8 and wanted more sound I'd just get an electronic sound booster upgrade. There's only so much you can do to make a 3-cylinder sound better. I've heard many aftermarket exhausts for this car and even a muffler delete - they don't improve the sound much and cost a lot. Boosting by artificial sound is the only way to make this car sound the way it looks short of an engine swap. Yes, it's fake but 90% who hear it won't know and will spare the driver an embarrassing subcompact soundtrack to an exotic looking ride.
Alex Myers of Yorkshire DPF Centre has just developed a new exhaust for 1/4 of the Fi price. I'll be getting one soon to test. From the data he put out, months of testing has resulted in better wave forms that compliment the electronic exhaust sounds. I'm looking forward to this.
@@PatsGarageOnline OK, definitely want to hear this and await your review.

👍👍👍👍👍👍👍👍👍👍👍👍👍
lol great find
1 person is just jealous they dont have an I8
It's probably the kind of person that sees an i8 go past and whilst his friends are impressed, he smirks and says "yeah but the engine noise is fake, it's not a super car, it's slower than a tesla" blah blah blah.

Who would do this? Your efforts are good, but this is too “ghetto” for a i8.
That engine cover really needs to be carbon skinned professionally. Car deserves it.
Yep, it was a first time playing with CF, so I wasn't 100% happy with it either. I considered sending the stock cover out to have it done by someone with more experience. I might consider doing just that.
Pat's Garage Online wasn’t meant to be a criticism. Good to see someone not afraid to try something different.
I’m looking a buying a i8. Never considered one before as I was not a fan at launch. I just read £129k and a 1.5 mini engine and stopped at that. Great value now though.
@@kevinkeelan354 It feels like a good value for sure. I'm noticing an uptick in folks visiting and commenting on my channel that they are in the market for one. In the US, the virus is causing sellers to accept offers up to 15% below asking price for exotics and sports cars. So now feels like a great time to buy.
Interesting fact: The i8 cost more to build than what BMW sold it for. I think the price, new, is wildly overpriced as well. That money would make a great down payment on a new SuperCar.
