- Today we install a Stillen cat back exhaust on a VR30 powered Q50 and we show you how to remove the stock exhaust on your Q50 and how this one is pieced together. We sound test the Stillen exhaust and throw it on the dyno to see how much more power it makes.
If anyone is wondering, Stillen catback on a 2018 Q50 redsport: Improved performance doesn't exist until you hit high revs. The sound is good and at highway cruising speed (low revs) the exhaust is pretty quite.
This applies to the non red sports as well?
I attended a showing of the new Z on September 23 in San Jose California and was able to hear the engine as the Nissan rep reved the engine. That engine sounded like a sewing machine, and so this VR30DDTT engine is going to need some kind of serious exhaust mods to make it sound decent. I could see where maybe an Infiniti buyer wanting a quieter engine but I don't think that any new Z buyers will be happy with that anemic sounding engine.
That was awesome. Very good, clear, and thorough video of the process. Makes my eager to do my Q50 plus LDPs, but waiting for the warranty to expire :(.
LDP shouldn’t void warranty
Great vid. Wish the new pipes didn’t have so much bounce. Stillen should make an upgrade to the mount bracket for a tighter fit
agreed
Great video! I wanna hear what she sounds like with downpipes!
Please if you ever get the opportunity to do a GThaus exhaust with downpipes! Do a video!
If we ever get the chance we definitely will
What you don't check the tip alignment before tightening all the clamps?
380whp/420ftlb on mustang. Dynojet should read 10% higher or so. 415whp and 440tq. This thing rips.
Thumbs up. Thanks.
I changed mine in an apt garage with jack stands. It wasn't too bad. 3.7.... Ark Grip CBE.
Had to take it to a shop to change the Motordyne ART Test Pipes tho.
ARK Grip came with hardware. I'm glad because some bolts snapped right off.
👏🏻👏🏻👌🏻❤️ great sound
I loved everything about this video right up until the end when you only gave 'After' HP numbers and not also 'Before' numbers, for a worthy comparison. What are we supposed to do with After-only numbers???? What gains were had from this Stillen exhaust???? Was planning the whole time to give a thumbs up but had to give a thumbs down at the end there. :(
And please elaborate on the 'flash tune'. What does that mean?
What? The car was bone stock so just look up the hp of car which is like 300
@@Trojehem that's not whp though, and he said the car with Stillen exhaust has 320 whp. Need to know what stock whp is. It might actually be significantly more or less than 300, so not telling us the stock whp made his statement kind of useless.
@@below90hz these cars say 300 on paper but dyno at 315 on avg.
@@XxGunsling3rMODExX whp?
@@below90hz yes. Same with the 5.7l hemi. Those dyno closer to 400 than the 372 they have on paper
Nice video bro
I wonder what this did to the MPG.. Most people dont care about that but sometimes I drive my car through 2 time zones.
Why didn't they go true duals like other manufacturers? The one pipe is kinda janky doesn't really scream out performance looks factory.
Are you guys located in Phx area? do you guys install parts bought by customer or only parts bought threw you guys?
DO A Q60 CZP CATBACK INSTALL PLS i'm actually looking into buying one myself
You didn't put the chassis brace back on after installation. Not necessary?
Will this void warranty since stillen is a Infiniti recommended part?
It’s literally a straight pipe with 2 little mufflers
What exactly are those wheels? I'm wanting to get those.
What was the power gain? Did you dyno before?
no real power gains without a tune. we did dyno it but no base before we put it on. we played with tune and were able to easily gain 15 horsepower but it was mostly just making the power band more smooth and consistent. watch the next video to see what we were able to do with even higher flowing system
Concept Z Performance but is it true by tuning your engine means wearing down ur engine life
@@threepac1342 great question.... Shame they didnt answer. From the factory, your vehicle is most likely designed to 'last' as long as possible.
If you fiddle with the settings it can change the life of your machine. Doesnt mean that it 'will' change the life. Just that it 'may' change the life.
@@threepac1342depends on the stage of the tune but it does lower engine life
Wheelz?????
Круто!!! 👍
320 ? That’s it , it does 328 stock
Great vid. Exhaust: to much bass for my taste.
why arent the muffler tips installed flush?
hey do you know what the size of the gaskets are
2.25" 2 bolt gasket
conceptzperformance.com/vibrant-performance-1457-exhaust-gasket-2-bolt-2.25-1456-universal_p_37641.php
I recommend these right here
Would this fit a 3.7?
Hi
What size gasket did you used ?
Hi! I got a 2018 Q50S 3.0t. Just wondering is the system same as the 3.7 Q50S?
This isn't a 3.7, but yes, you can. From the catalytic converter back, everything is interchangeable.
Does that means you get no gains at low rpm?
When you open up the exhaust it usually takes away from lower RPM torque and adds it to higher rpm gains. Happens with almost everything from my experience. The exhaust has built in resistance that helps create TQ at lower rpms. Remove that resistance and the TQ goes away at lower RPM.
Not 100% of the time but it happens.
What suspension is the car on?
Are you guys in Costa Mesa CA?
Stock exhaust has heat shields would this kit make the cabin hot
no, there's a lot of material from metal and carpeting that blocks the cabin from the exhaust also that heat shield is on the cat which is intended to heat up faster than just a straight pipe.
No even... Q50 body is made for the Q50s RS. That is the same engine with a factory tune. but it runs hotter. They use the same under pinnings for heat shielding.
Sounds like a moped
maybe a 20-35 Whp increase with that exhaust + tune? That's booboo actually for the 3.0t - I've seen the ECUtek take these to 400+ HP with just intakes and a tune.... whats going on here?
Exactly what i was wondering
God that Tip Alignment is horrid :(
320 WHP sorry yah no Weak dyno i guess.
Hi can help me I need knows size pipe to q50 3.0t original I want change to carbon fiber need size
What tune..? Arent these things supposed to make 400-420whp with just exhaust and jb4 tube..?
This isn't a Red Sport, Silver Sports only make about 300 crank horse power
Concept Z Performance yeah the silversport is what im talking about, theyre making 400-420 off of just tune and exhaust, maybe downpipes too.. thats why everyone is getting the silversports instead of redsports lmao...
on our mustang dyno it reads a more accurate wheel horse power. 400 to 420 is what is usually read by other dynos. Those aren't entirely accurate
@@nccra826 the red sports dyno 405WHP/454lb ft of tq with a simple JB4 flash on +4 psi and zero bolt ons..... Takes a lot of other money and work to get the silver sports there.... (I.e- downpipe, full tune, +7 or +8psi, heat exchanger to handle track or repetitive runs, intakes....)
Would it be better to tune my 2019q50 before or after I install an exhaust sustem
*System
Always tune after any bolt ones
Motordyne
Good on 3.7
Then the belt shreds opppss!! 3.7 all the way
For the 99% of the time it's not shredding belts it's out there killing 3.7's
@@sikh70 how so not realiable then the na 3.7 facts
@@balesha85 stop hating unless you've owned both platforms. 45,000kms on my red sport without a single belt issue.
@@sikh70 ai have owned both got rid for the 3.0 ask anyone 3.7 is more reliable facts bro ask your Mechanic
@@balesha85 I didn't say it wasnt reliable. The VQ is far more reliable than the VR.
im sorry, but i'll always prefer the sound of the 3.7 VQ over the 3.0 VR...sounds like a mix between a blender and a Dyson vacuum cleaner :(
Hows the drones?
actually pretty quiet, I'd say there really isn't much especially if you only get rid of the lower cats and keep the upper cats like we did here. practically none
Concept Z Performance thanks,about the tip sticking out can we adjust that?
slightly, they can stick out more if that's what you're looking for and they can go in about another inch. They won't be flush with bumper, but you can also just not put the tips on if you don't want anything sticking out an inch or two
how many hp does it gain? if any?
car had an odd flash tune and made about 15hp, with a good tune and the increased airflow you can see about 40. come back soon and watch part 2 of this
vr30 with a flash tune still 320whp? What a poor tuner.
oh, just wait and see. we will go further into this in the next videos. we were surprised on what it was making too
It's on a mustang dyno, don't those usually read lower than dyno jets?
yes, but id say its more accurate. Dyno jets in our opinion are more inflated
What a piece of garbage that exhaust is.
I thought it had 320hp from the factory smh y’all suck at tune
