new member here, I just bought a 1989 grand prix turbo 33,000 miles looking to open up the exhaust, having trouble finding a performance cat back system anyone have some ideas on an upgrade for this car that bolt right in?
 


I think dynomax might be the only aftermarket vendor still offering a catback for the older GP's. Not really sure if it's availiable anymore though. I had a 1994 Cutlass Supreme and there was literally nothing. Ended up just having a custom setup done with a high-flow converter and full 2.5" pipe to a custom Y-Pipe and some stainless mufflers. It's not hard to make the 3.1 sound good in reality.
 
Welcome you can find dp at zzp and a few other places I got mine from O'Reilly's 3in Magnaflow but that's for supercharged if you have a turbo zzp should and again welcome and good luck
