I'm new to this site and 3rd gens, so please be gentle. I have a 91 GTA with a 305 tpi and I'm installing a 91 350 tpi with A/T. I have to stay emissions legal. I decided to go with Hooker 2055 with the y-pipe. I'm looking for someone that has installed a 86-89 exhaust on a 90-92 TPI bird. What brand cat and the rest of the exhaust did you use? How did it fit? Any mods? Thx.

MPE-23479 - Dual cat set-up


I have been looking into the magnaflow dual cat set-up for my 1991 GTA 350. I like it because it is all welded together. just bolt it up and you are done! I have emailed Magnaflow tech and they are great.

I have SLP headers and originally went with random tech cats. after going to muffler shop and having the monkies do a half *** job I would recommend staying away from that route. I also have dual cats which made it that much worse

I have not purchased anything yet but Magnaflow looks to be the best way to go.
