Hey everyone, I was just wondering if there is anyone running a turbo setup with a high flow cat. I know most people don't and that reflects the big numbers that they gain. I wanted to run a high-flow cat to reduce the scent of the test-pipe and was wondering if anyone is running one. I'd would be okay if the cat robs a few ponies, but keeping the scent down while maintaining decent power is my goal. There wasn't many threads that gave me a clear answer when I searched so I decide ask you guys. I will be running the Ultimate Racing kit, just waiting on shipment. Thanks!!!

I am new so don't hurt my feelings too much!!! :D

do all cars smell that bad???? My test pipe is on the way, I hope it doesn't smell terribly bad :(. Maybe my huge resonator will soak up some of the fumes?

Yeah, I know my buddy with a RSX with SC-61 smells like SH**. And I don't want to be like him :)

How is the Invidia exhaust boosted? Still as loud as NA?

I have the Invidia V3 witht he Greddy kit, and at first it was miserable, now its bad, just not as bad, I ordered a 3" Vibrant resonator. I would rather hear the Turbo Spool, then the exhaust

Baby killers! :D

I have the Berk high flow cat, which is a noticeable improvement over the stock cat. I've never run a test pipe so I can't compare it, but the high flow cat was flow tested to be 87% of a straight pipe.

being that turbos respond VERY well to VERY high flow.... I would never cut down on flow on any turbo vehicle. I just wish I had 3" exhaust the whole way back.

I might go with high flow cat from berk and custom 3" exhaust. Any suggestions on what kind of muffler I should use?

I got a 3" megan racing exhaust for 408 shipped from ebay. Its loud but sounds great. Fit and finish are great.

Is this with 3" piping and everything thing bolted to the cat/test-pipe?

The problem I have with this claim is what percentage flow does the stock cat have in comparison to the test pipe?

I went with the Invidia V3, the downpipe is less then 3" so I figured it wasn't worth the $1,000+ for a custom 3" Exhaust. I have the Invidia V3, getting a Vibrant 3" Resonator and a test Pipe, should be more then enough room to push the air through, Im getting it tuned and Dynoed on the 4th, Il post the results, still undecided about upping the Boost to 9-9.5

43%, which they posted. Looking down the stock cat vs. the high flow cat, its easy to see why.

So I am assuming most people either run a cat-back or turbo back. Do you guys do anything about the smell or just deal with it? Just curious.
