Royal Enfield Classic 350; DNA Filter and Stage 2 cover -De Cat and short Bottle exhaust - result!

- Finished setting up my RE 350 Classic with the CAT removed and free flowing hot bottle exhaust and DNA Air filter and stage 2 cover, result is a far better running engine that pulls higher gears at lower revs without that strangled engine lurching as before in stock set up. It tops out at 75 mph on stock gearing for those interested but that's not what this bike is about..impressed with the changes, costs;
DNA Filter with stage 2 cover available for £75 if both in stock at Hitchcocks UK
Cat replaced with 42mm OD stainless pipe - £8 on eBay
Steel black short bottle exhaust from India - £54 on eBay

New owner of Desert Storm edition, classic 350. Always appreciate upgrades videos keep them coming !
Hi Joesph, thank you and hope to keep the films coming!
Cheers

Hard to concentrate when our host is standing in front of one of the world's most coveted Jeeps. Looks immaculate. 1st time viewer.
Hi thanks for watching a nice you appreciate the Willys Jeep!
I have a playlist on the Jeep you view on my home page 😁👍 cheers Bruce
Will do, thank you.@@Coastriderscotland
I ordered a 350 classic on Sunday, same colour, looking fwd to getting it, already been on hitchcocks site looking for goodies, defo doing the de cat etc, got a dna on my interceptor 650 and does make a difference 👍
It certain sly goes better with a few small changes, well worth doing 👍😁 cheers Bruce
That was interesting and informative thank you.
Glad it’s of use to you Tom!
Cheers Bruce
I'd love to see pre/post dyno runs. It's always hard to separate real performance increases from extra noise.
Hi Martin, there is a guy did some dubious runs on here after these same mods that I follow, look up Black Phantom Rides
Cheers Bruce
I installed a DNA filter and cover about 6 months ago on my Meteor. The sound is wonderful, and it is a lot peppier. 😎
Brings the bike to life, I love the noise now!
Cheers. Ruce
Witaj , na forum angielskim ktoś pisze że po zainstalowaniu osłony i filtra trzeba przez 15 minut zostawić silnik na wolnych obrotach żeby ECU się zaprogramował, też tak musiałeś? Czy to jakieś brednie😂
Yep , magic bit of kit.
Looking at the filter and new cover cap, it looks like the space I use for docs in the side should be taken out. Wondering if the cover allows all the free breathing that the new cover allows?
I could put the docs on the other side I suppose - not as nice, but would work...
Might just order these and the 16-tooth sprocket as well. Fun to do some simple upgrades with Fall weather coming!
Ride Safe 🙏🏼
😁👍
Ordering one ASAP. Wish I had been paying attention to when the GBP dipped to almost even with USD a couple weeks ago I could have saved about $10 😆
Hi Alex, you won’t be disappointed with one of these cracking value wee bikes! 👍😁
Cheers Bruce
Really good video, especially offering the cheaper alternative to the decat - a bit of common sense applied! Out of interest, where did you get your pannier rails from?
Hi Alex, the pannier rails and panniers. We’re from India via eBay, sadly they are copied and not genuine RE items and poor fitting with wrong length bolts etc and rusting already at the welds and not on salted roads yet,
Cheers Bruce
I ordered one from eBay too. The panniers are terrible quality. I do not recommend them at all. It was real waste of money. Racks are so-so. If you do not mind a bit of drilling/filling to fit them.
Hi fella, Great blogs,has the new filter affected your mpg?thanks.
Hi Noel, I think because the bike breaths better you done now have to rev it as hard and so it has improved mpg, this along with slightly higher gearing dropping the revs in 4th and 5th
Cheers Bruce
Great video!🙂 One question when it comes to RE’s 3 year warranty. If anything should happen with the bike, will the mods affect it when the question of if the warranty will do the coverage comes up?
Any experience or knowledge about this?
Hi, not sure on the warranty effected or not, you can always refit the stock parts if it needs to go to a dealer I guess
Cheers Bruce
Hi, thanks for sharing. I have already done the Hitchcock’s decat, intending to go down the dna stage two, but also considering fitting a “Fuel X” controller. What are your thoughts ? Ps, have subscribed 👍
Hi Ian, I was hoping someone else buys the Fuel X controller and can report back on any improvements before I shell out on one! :)
@@Coastriderscotland it might be me then, I will no doubt put my thoughts on my channel 😉
Check out `Tiger Ness` channel. He has just done that mod to his Classic 350 red / chrome model.
Does the exhaust stink without the cat or it it passable? SUBBED also. Great channel
Not at all there is no smell at all without the Cat, of interest is here in U.K. the Cat is not compulsory for MOT, it must be required for certain other euro countries, I’m going to replace the bit pipe I used for a U.K. Hitchcocks CAT replacement pipe - just to smarten the bike up 👍
Thanks for the Sub!, appreciate it along with any other future comments you have - CZcams like it!and Iit helps the channel grow 👍😁
Cheers Bruce
With regards to the stage 2 cover,do you think the standard cover could be opened up with a hole saw and cleaned up with a smooth file then replaced? Or would a hole interfere with fitment after?
Hi Mark, I have seen some people post in the past they had cut the original cover and opened it up with a drill,
Some people fit both DNA and Stage two as I did, some just fit the DNA filter and leave the box stock, some leave the stock filter and fit the freer breathing stage 2 end, I bought the DNA as it’s washable an so reusable which I like, and at the time the stage 2 end was also in stock at Hitchcocks U.K., but I’m sure if you drill the original cover you should get te sane results at the stage 2 end cover, hope this helps! 👍😁
Cheers Bruce
Thanks for this video . Can you tell me where you got your rear rack from ? and link to buy one ?
Thanks .
Hi, I bought the pillion repair rack from India via EBay and it rusted quickly hence the respray, Hitchcocks U.K. are now selling them and they are U.K. made for same price around £100 so should be better quality! 😁👍
Cheers Bruce
Sir can you tell me where you got the rear rack? I love the look, Thank you!
Hi David, I bought the pillion seat replacement rack from Raju Lax a Rae dealer in India who is on the U.K. Rae Classic 350 Facebook page, he is used by many in the U.K. with quick delivery and good and safe to use, the rack was from memory approx £115 posted and arrived in under 2!weeks with no duty to be paid (being under £150)
Cheers Bruce
Hi, does your tank rack use suction cups if so, has it ever come off? As I've seen some of the terrain you ride on . Nice pipe btw.
Hi Rockintigger, the tank rack stayed secure but I only used to bungee waterproofs on it, but once I had painted the bike green the suction pads would not hold it secure enough to trust it, possibly from my rough paint spray!, so I tgen used magnets from cheap Chinese Go Probmagbet mounts but the threads are really not long enough-I solved this with a dollop of Arladite rapid and it’s solid now 👍😁, but on your stock paint the rack is firm enough stuck 👍😁
Hope this answer helps you 👍
Cheers Bruce
Hi, many thanks Bruce, that deserves a subs. an a 👍 I’ve got the basic 350 Meteor in red an that little rack looks perfect. I’m also decatting her (sounds painfull without anaesthetic 🥴) but it looks like I’ll have to lose the centre stand as the cat’s got two rubber stops it rests on, but I’ve got a paddock stand to fall back on. Happy we’ve got the extra hour, all we need now is a bit more heat.
Piet, the southern softy. 🤭
nice video!!!
question....why DNA and not the famous K&N airfilter?? just very curious....thanks!! Wim😉👍
Hi Wim, the DNA make of filter seems to be the choice of Hitchcocks U.K. to sell along with the stock filter 😁👍
Cheers Bruce
@@Coastriderscotland Thanks Bruce......i am getting more and more in love with such a beautiful bike.....love it,also in the "army colors" cheers!!
Sounds wonderful!! Does it effect the fuel range ?
Hi Michael, it has not made the fuel economy any worse, I have been using E10 fuel and filled up yesterday with E5 97 Octane and going to record MPG and try work out if pence per mile is cheaper if it improves economy?, only one way to find out!
@@Coastriderscotland And? Did you find out what the consumption is now?
I have the DNA filter 2stage kit which is great. Even sounds better! I do like the look of the original exhaust though on mine. I no you can just de cat it! But wondered what your thoughts on knocking the cat gubbins out of the standard pipe 🤔 and re fitting it? Only issue could be not time in 3 year's. What do you think ? Does it feel considerably more torque or not! The air filter has made a difference already. Not bothered about speed at all though. I altered my thruxton baffle and lost mid range torque until I fitted a K&N
Hi Robert, I think the mid range increase is part de cat and part DNA filter - that’s just seat of the pants feel not on a Dyno etc, think best keep the CAT complete and just buy the Hitchcocks de cat mid pipe for the £90 and use stock silencer and see how it goes?, prob best keep the CAT for future MOTs as probably expensive to purchase new going by car prices
Cheers Bruce
@@Coastriderscotland yeah that's what I thought. It's the potential MOT thing going forward. Thanks for your thoughts 👍
My choice: I used Stage One only on my Meteor: Original filter, but with the new big hole from DNA (from 40, to 55 mm direct blow). Ride safe.
Defo worth doing! 👍😁
Cheers Bruce
Really interesting video !
I am sure 75 mph is fast enough for this type of bike and those roads you drive.
I think I read somewhere that the top speed is electronically governed anyway.
I think the limited top speed is 114 km/h or 71 mph..
@@andersbarfodsvaneskolan9378 Mine is 120km/hr. The bike surges slightly at this speed. If I pull the clutch in there are more revs available, but the bike wont go faster. I think it is to save too much stress on the (small!) motor...
😁👍
That dna stage 2 set up is £89+ on hickcocks now as at 10th Nov 22
That’s quite an increase, everything is going up in price now it seems
Hi!
After one year how is the bike?
Did you use a FuelX after all?
What are your thoughts after a year?
I heard that the FuelX is a good option to get the fuel mixture richer and lowering the temperature of the motor!
Looking forward to you reply!
Tks
Hi I did indeed fit the fuel X lite and forgot to mention it in my 10,000 mile review film!
But yeah bikes going great and never missed a beat! I’m looking forward to more miles and smiles on the bike! 😁👍
Cheers Bruce
@@Coastriderscotland tks a lot for your return!
Do you recommend FuelX, like mandatory or not?
Tks
Sir please i request you to make a video on cat removal of royal enfield hunter 350
Hi, i own a Classic 350 but sure someone on CZcams has done similar on the Hunter 350
Cheers Bruce
did you replace this straight away or did you wait until the bike had a bit of mileage ?
Hi, I waited until 1st service - which was late at 800 miles then once 1000 miles in I swapped the pipe and cat then just got the DNA filter last week with 2000 miles now on the bike
Hello Coastrider, thanks for the video.
i recently bought the DNA filter for my classic 350 reborn without the air filter cover. My question is can i still install it using the stock filter cover ? Thanks for any advise.
Hi, im sure you can still install it as size is identical
@@Coastriderscotland thanks, i did already installed. will order the DNA cover to try though. Thanks again :)
@@stpatrickchai I felt that the DNA filter had double as much gain without the stock cover as is. I just sawed off the snorkel on the stock though.
@@Coastriderscotland Thanks Mate. just received mine and yes it does fit. Probably next step I will install the DNA stage 2 cover. Heard many good reviews on that too.
Is it necessary to run a FuelX or something to compensate the air fuel ratio when making this mod? Or will the stock ECU compensate itself?
Hi Paul, good point which I think I will still add one when the cash is spare as it should keep the mixture level perfect 👍
Cheers Bruce
Can I ask which make of panniers they are that you have fitted and where you bought them.
Hi Andrew, I bought these on eBay via India and although approx half the price of those here in U.K. and waterproof they are it turned out copied and the left pannier frame is made wrong and the pannier bag does not sit on correctly. Hitchcocks U.K. did not have them in stock when I bought the bike in July and I now wish I had waited and got genuine ones once they were available here in U.K., the old saying ‘buy god buy once’ is a true saying!
Cheers Bruce
I have just changed my filter and free flow cap. I noticed that you didn't refit the outer document holding cover. Why is this? Do you think that this outer cover might restrict the air flow?
Hi, I never fitted it as other people did the same on there videos 😁👍
Cheers Bruce
Hi! Would it work if stay on the stock air filter and put the dna air filter cover?
Im sure you would still get a noticeable mid range power improvement doing so 👍 maybe not quite as much but the Cam deft does make a noticeable improvement 👍😁
Hi am new to this so what exactly is "de cat" and is your short bottle exhaust a total exhaust replacement? I get the filter replacement bit. Thanks.
Hi the decat is just a less restrictive mid pipe that allows the exhaust to breath easier along with less restrictive silencer, it only makes a small difference to mid range power but i like how the bike sounds modified, more like a classic should 😁👍
Cheers Bruce
@@Coastriderscotland Hi Bruce thanks for the info cheers. Gary
I plan on doing this. My signals gets delivered next Friday. I have a question, what are the tank and bumper rack and where did you get them? Many thanks mate. 😊
Hi, tank rack is available from Hitchcocks U.K. for about £30, and te pillion seat replacement rack was bought on eBay via India for Approx £100 posted 👍
Cheers Bruce
@coastkid71 cheers Bruce. Only got my big boy licence yesterday. At 57, I'm pretty late to the game. Really excited. I live in County Durham so lots of country roads and the coast isn't far. Brilliant!
@@jez6208 your in an excellent area for riding a Classic 350, and not too old at all to start riding! Have fun on your adventures on your 350! 👍👍👍😁 cheers Bruce
@coastkid71 Thanks Bruce. I can't wait. I'm going to get up really early. Ride to Whitby. And watch the sunrise. 👍
Can you share the link for the carrier at the back of the bike
My rear rack came from India and rusted quickly! Decent quality pillion replacement racks made here in the U.K. are now available from Hitchcocks U.K. 👍
Cheers Bruce
can you tell me where you bought the rear rack? Is the carrier still from the old model (before 2022)?
I bought the rear pillion seat replacement rack via Raju Lax who has a RE shop and posts to U.K., cost approx £110 and arrived in just a week! Search for him on U.K. Classic 350 group in Facebook
Cheers Bruce
@@Coastriderscotland many thanks Bruce !
Have you noticed any difference with the fuel consumption? Have heard people say their consumption hasnt changed at all with similar upgrades
Hi Kaptein, not noticed any change in mpg, I cannot get lower than 8o mpg even gunning it! 😁👍 I think maybe with the engine being able to breath with the DNA/stage 2 and cat removed let’s the engine pull better without having to open the throttle as full, to be fair it’s only a 2 valve 20 bhp 350 but these small changes help make the most of only 20 bhp 👍 cheer Bruce
@@Coastriderscotland Thanks for the reply. Thats very usefull information, thank you
@@Coastriderscotland Btw, are those imperial or us mpg?
@@kaptein1247 imperial mpg 👍
Aren't you supposed to let it tick over for at least 15 mins then leave it for a bit before riding the bike? Some about letting the computer adjust for the increased air to fuel ratio or something? I'm just about to do this later today.
Hi Jez, I’ve read 2 minutes, 10 mins, and 15 mins so I’m not honestly sure which time to idle the bike for is right 😁
Best you go 15 minutes to be fully sure, time it will take to go make and enjoy a coffee while waiting 😁👍
Cheers Bruce
@@Coastriderscotland well, I fitted the filter and the cover plate. Left the manual holder thingy off. Worked like a charm! Big difference in torque, throttle response, and exhaust roar! Brilliant! I really didn't think it would make so much difference. Christ! I hope I don’t knacker the engine?
Hello! Do you think it's possible to use the stock muffler with the straight 41 mm pipe? Thank you!
Hi, im not sure and my pipe is now in the loft in storage until if needed for the 1st MOT, but if you buy the De Cat mid pipe from Hitchcocks UK the stock silencer fits back on
@@Coastriderscotland thank you!
Does the fuel injection system recalibrate itself due to the increased air flow. If not won’t the bike run lean and hot ?
That is really the main question. Would be nice if someone has got an answer.
Also to see the color of the ignition plug before and after installing the DNA filter says a lot about if everything is working fine.
@@dertechniker8867 Instal cold and then after fitting, let the engine idle for 15 minutes (without revving) to let the ECU recalibrate.
I believe as mentioned in above comments the fuel system seems to reprogramme itself - it is quite hard at first to have the faith it’s ok - maybe that’s after years of old carburettors on motorbikes! 😁👍
Cheers Bruce
I'm thinking the filter swap would improve performance even without the cat removal....
The bike is definitely running a bit cooler with the cat removed- which must be a good thing, but yeah the change in filter is probably the most noticeable improvement in improved power at low to mid range through the gears
