I have a 1989 Trans Am GTA with a 383 strocker and dual stock cats. I'm thinking of taking my cats off, and I'm wondering if I would notice any gain in performance?

 

You'll pick up 5-10 I would say since you have 2 of them. Why not just get one hi-flo one?

 

hey SMKNGTA,
I heard that you hafta do yearly maintence on the 383stoker, with working on the pistons and rings.. is that true or your engine is to soon to know yet?

 

I'm no expert, but how could that be true? It's the same as every other motor. And if you had to do maintenance ont eh rings and pistons, I don't think anyone would build a 383. Course I may be wrong.

 

I felt a major gain with my 92 Z28 convt 305TPI when I gutted the stock cat. I can only imagine your 383 would really breathe with out the cat. Beware, your exhaust will become noticeably louder without the cats!
I'm running a single, high-flow cat on my ZZ4TPI combo, mostly to keep the exhaust note reasonable. I'm a little older and get tired of the "open exhaust" sound I loved so much when I was 17!

 

it would be worth the effort, and rob's right, it will get louder. of course i like mine that way, i'm only 20!
