I’m Trying to find the best exhaust for my 01 Tran Am. It’s now a 383 stroker and I’m having trouble finding a complete new exhaust from headers back. Do I have to run cats so the O2 sensors can register? What are some setups you guys have had success with?

 

Have you looked at all the major vendors on here that deal with exhausts? There's several of them

 

Are you using o2 sensors?

 

I'm running Texas speed LT's with there ORY pipe to slp loud mouth catback. Great flowing setup and not real expensive

 

I don't know anything about 383's, but I know with the 98-02 LS1 F-Bodies you need the Front O2's for AFR feedback in closed loop. The Rear O2's only exist to tell you if your cats are working or not. You can get that light for the rear ones tuned out if you don't want to run cats. My Rear O2's are literally just ziptied up under the car now that I have catless Headers/Y-pipe.

 

Before your question can be answered, we need more info.

Do you care about noise level? How quiet do you want it to be?

Do you care about smell?

Do you want the flexibility of having it be as great flowing as possible for maxium HP while being loud, while also having the flexibility of having it quiet when you aren't needing it to be free flowing as possible for max HP? (note max HP is only 10 HP difference if that)

Are you lowered or do you plan to be lowered? (potential clearance issues with certain setups)

You don't need to run cats for the O2 sensors to register. You would just run the front O2's and get the car tuned for that setup.

 

It’s just a weekend cruiser and I’m looking for HP gains and a deep tone, but not so loud it will get old on a 2 hr
trip down the highway. I have a medium aggressive cam in it. I have shorty headers with factory exhaust besides the muffler being deleted now. This is my high school car I never let go I’ve been building up. Thanks for the input

 

I'll send you a PM.
