Perrin 3" Resonated - Going Turbo - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

airindia33 · 02-02-2021, 10:22 AM

Hey Guys. I have a few questions. I recently bought a 2020 BRZ PP.

Ordered a JDL Turbo kit (GTX2867R) with EL Manifold. I also plan on going with a full 3" exhaust system (tuner's recommendation). I have also ordered the resonated (single) over/front pipe combo from JDL and finishing it off with a 3" Perrin resonated catback system.

Since the JDL parts are 4 weeks out and the Perrin system was already in. I decided to put the system on and I do not like it.

Remember I am currently fully stock.

At idle: the system is very close to stock, not obnoxious at all.
Going up in the revs: the system is deep but definitely has drone.
Going down in the revs: the system has uber high levels of drone.

My question: Will the system sound totally different after the turbo kit and over/front pipe are installed. Is there a chance all the drone is just due to having a 3" system on a stock header & front pipe???

If anyone has a turbo kit and is running the perrin system I would love to hear your feedback. Thank you in advance.

Interesting you might be the only person i know off that is experiencing drone from the Perrin exhaust either that or something is wrong with your install. Make sure everything is tight and check the vband connections.

Yes once you put the turbo it will sound different usually putting on a turbo quiets things down slightly ,but since you're installing an EL header and the OP/FP im sure it will have a good tolerable sound shouldn't be obnoxious. Im not running this setup so take my input with a grain of salt...

The car will sound different; a turbo is like a muffler. Just be patient and wait to see how it sounds

Install is perfect. I will be patient and see how it sounds after all the other mods are on.

Yeah just wait and see how it goes. The other option is Invidia Q300 which is also supposed to be a quiet no-drone exhaust.

I am trying to stay at 3" all the way back based on my tuner's recommendation. I also don't mind moving to something louder as long as there is minimal to no drone.

This isn't my daily driver...

Ok so update. Finally got my full JDL kit in last week and installed this week. The install was fairly straight forward and am very happy with the gains. Unfortunately the exhaust still has a horrible drone from 2750-3400...

Any other recommendations of exhaust systems?? Would like to stay 3” or 2.75”. Don’t mind louder as long as there isn’t drone.

Does the OP/FP have a CAT?

MotoX16 · 04-19-2021, 03:30 PM

I have the same setup as you except I went with the dual res FP/OP. Personally its just right for me.

I've heard a slightly quieter catback is the CSG one but that does step down to 2.75"

Heres a quick dyno pull with my exhaust

Chuckls · 04-19-2021, 03:52 PM

I currently have the perrin 3inch on my turbo BRZ. No resonators in my "front pipe"
3400 rpm does have some drone, but it's much better than my Tomei I previously had

jflogerzi · 04-20-2021, 12:56 AM

Get the CSG Touring 86 by MXP. The minor step down in size wont restrict till 400WHP.

Have you checked out https://www.ft86club.com/forums/showthread.php?t=143514 ? This might fix or at least alleviate the problem, people seem to comment on the fact that this fix removes resonating noises around the 3k RPM mark which is what you're facing.

I also installed the same catback (Perrin 3" Resonated) this weekend and am getting a lot of cabin noise and drone, especially when cruising at those rpms. I can't say for sure this will fix my problem as my front pipe has a blown out cat. Already ordered the hangers and should get a new front pipe soon
