Infiniti Q50 VR30 Stillen Cat Back Exhaust Install / Sound / Dyno

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.

[@AGCampagna]

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.

[@DanielCruz-js4oh]

This applies to the non red sports as well?

[@user-hg5se7up6l]

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 :(.

[@WWF90904]

LDP shouldn’t void warranty

[@videomaniac108]

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.

Nice video bro

[@Yousu_ali_]

👏🏻👏🏻👌🏻❤️ great sound

[@paulbutikofer4284]

What you don't check the tip alignment before tightening all the clamps?

[@Zswag22]

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!

[@Conceptzperformanceczp]

If we ever get the chance we definitely will

[@doggystyledave]

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.

[@rsloyan1]

380whp/420ftlb on mustang. Dynojet should read 10% higher or so. 415whp and 440tq. This thing rips.

[@juanserrano6457]

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

[@Conceptzperformanceczp]

agreed

[@salazeezee]

You didn't put the chassis brace back on after installation. Not necessary?

[@pvblito]

What exactly are those wheels? I'm wanting to get those.

[@brycef7130]

Are you guys located in Phx area? do you guys install parts bought by customer or only parts bought threw you guys?

[@calebgrove606]

Will this void warranty since stillen is a Infiniti recommended part?

[@nonickname8292]

I wonder what this did to the MPG.. Most people dont care about that but sometimes I drive my car through 2 time zones.

[@CrazyGreek80]

Why didn't they go true duals like other manufacturers? The one pipe is kinda janky doesn't really scream out performance looks factory.

[@tomaszoledzki]

Great vid. Exhaust: to much bass for my taste.

[@g95t2000]

hey do you know what the size of the gaskets are

[@Conceptzperformanceczp]

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

[@Legitshooter]

Does that means you get no gains at low rpm?

[@nonickname8292]

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.

[@yannslii307]

Hi! I got a 2018 Q50S 3.0t. Just wondering is the system same as the 3.7 Q50S?

[@Conceptzperformanceczp]

This isn't a 3.7, but yes, you can. From the catalytic converter back, everything is interchangeable.

[@coly0226]

What was the power gain? Did you dyno before?

[@Conceptzperformanceczp]

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

[@threepac1342]

Concept Z Performance but is it true by tuning your engine means wearing down ur engine life

[@nonickname8292]

@@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.

[@WWF90904]

[@oscaraguilar7903]

Stock exhaust has heat shields would this kit make the cabin hot

[@Conceptzperformanceczp]

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.

[@genkideguire]

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.

[@ptatohed4471]

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?

[@Trojehem]

What? The car was bone stock so just look up the hp of car which is like 300

[@below90hz]

@@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.

God that Tip Alignment is horrid :(

Sounds like a moped

[@nccra826]

What tune..? Arent these things supposed to make 400-420whp with just exhaust and jb4 tube..?

[@Conceptzperformanceczp]

This isn't a Red Sport, Silver Sports only make about 300 crank horse power

[@nccra826]

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...

[@Conceptzperformanceczp]

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

[@shad3128]

@@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....)

[@gamertyper6476]

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?

[@MIGGY912]

Exactly what i was wondering

[@jnagime]

Hows the drones?

[@Conceptzperformanceczp]

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

[@jnagime]

Concept Z Performance thanks,about the tip sticking out can we adjust that?

[@Conceptzperformanceczp]

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

[@hendryt588]

how many hp does it gain? if any?

[@Conceptzperformanceczp]

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
