I picked up a 1989 Pontiac Trans Am GTA with dual cats for parts. The engine in my 87 GTA blew and so i'll be swappin it out for the 89. My question is: what kind of headers and cat back can I use with the dual cat set up and wheter the stock dual cats would be better or a whole new exhaust system with a single cat???

Thanx

With cats be sure to order headers that have AIR tubes. Depending on your budget SLP would be the best, Edelbrock sells a set for around $300. As far as a cat-back, I would just go with a regular 1 cat, cat-back and I would recommend the Hooker. Sound clip is in the signature. I just ordered the cheap one and had an exhaust shop weld it on.
