is there such thing as a quiet 3" turboback?

Post by know1 »

I got a 94SS with Vf11 running a 3" cat-less downpipe to cutout/stock exhaust. I find it acts funny when i open and close the cutout too much (not too mention it boost creeps like a mofo) so I want to go to a 3" exhaust all the way with a hi flow cat somewhere in there. My issue is, however, I want an exhaust that will not be too loud. I still want to be able to hear my turbo, pbv (got the coffee mug mod) and cruise up to the house at 4am without waking everyone up (this is why i got the cutout). I have heard the flowmaster super 40 on a 3" with a hi flow cat on an ej22t and is sounds sick, but i fear it may be way too loud :P

any ideas?

sorry, I typed in no then forgot to change it. If you're going without cats and a fairly unrestrictive muffler it's gonna be loud. If you're using a cutout, why not use a stock exhaust and put the cutout before the cats?

I have a TurboXS (not the RFL) and it sounds much quieter than most. But still, even if it doesn't sound loud, the bass note carries, and people inside know when I pull up out front.

That is my exact setup, I have a 3"catless dp to my cutout then stock from the cutout back. My problem is that the car behaves weird if I open and close it to much. Also, when the cutout is open I get mad boost creep.

Rallysam, I realize I'm going to be somewhat loud I just don't want silly loud :P. Do you have any audio clips of your exhaust?

I am going to be installing the borla hush with a high flow catted downpipe in the future. hopefully, it's not too loud.

anyone else have this set up on their legacy ss with the stock turbo?

Let us know how it sounds...
I have a 3" DP to a Hi-Flo cat, then 3" pipe back to a Brullen twin tip. Great sound, quiet idle, really barks at WOT, but the drone at extended highway speeds gets a bit much sometimes. I'd like to fit a secondary silencer between the muffler and cat, something low profile and unrestrictive.

I used a EZR D/P connected to a custom cat-back that was made with 3" u-bends, straight pipe & a $25 summit-racing 3" oval muffler (fabbed up in my buddy's garage).

It sounds good - not too loud, but definately not as quiet as stock - nice deep tone.
My Fujitsubo (3") equipped OBS is much louder.

How bad is the boost creep with the cutout?
I was thinking about installing one on my SS.

My 3" turbo back ebay special with 2 resonators and a muffler is very quiet. I can barely hear it with my windows closed.

Borla hush is my favorite, and quietist Ive heard in the 3" flava.

Have a feeling the muffler isnt high flowing though.

Bingo! This is the key. If you run a 3" catted turboback with a muffler, add a resonator if its still too loud. And if you want even more quiet put on one more. You reduce the noise without adding restriction (except for the cat & muffler).

I listened to a large selection of them here. If the links are still good this is an invaluable resource...

+1 for the sound of the Borla Hush BUT -1 for them leaking like crazy b/c they are clamp type exhaust...

How about a stealth-back? That's what I'm running and sounds about like stock WRX/STi (just a 'tad' louder). Catless, 3.00" DP and MP to WRX axleback. Motor is a 2.5 w/VF39. BTW, the larger the turbine diameter and flow the louder it will be.

Edit: You're still going to experience boost creep unless you get a proper boost control set-up, either through EM or a standalone controller.
