any performance gain from replacing cat back? or just ypipe? Just purchased the Trans am and love it!
Headers seem like a huge project, something I don't think I could tackle alone. I was looking for some opinions.
I always want cats on the car, hi-flow cats are fine with me, but can I replace from the manifolds back? So a new Y pipe with hi flow cats, to the catback?
Is the stock catback restrictive on a bolt on car? Would it be worth the money to just swap out the Y pipe and weld in a new muffler in the stock catback?
