I have a stock 89 IROC with a 350. I have a 3" flowmaster cat-back system. Can anyone help my out with partnumbers or weblinks for headers and a cat to finish off my exhaust system? Also, where can I get the Y-pipe?

I know that I can research this and find out, but I'm at work and I have almost no free time.

Thanks

 

Call Summit up, it will only take but a few mins. I'd go with Hooker headers and a catco cat. They'll know the part #s you need, just be sure to get 3" in/out cat, and get the Hooker headers that come with a 3" y pipe.
