Exhausted 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?

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.
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

the set up i run on my car is 1 7/8 long tubes with a 3 inch x pipe and bullets dumped, cruising speed is nice but when you hammer on it theres no doubt there is an open exhaust would recommend to anyone
