Can you do us all a favor and list part #'s?
Re: Summit brand cat back exhaust?
Sorry here are the 2 I'm looking at. Not sure which one I need I think it depends on which catalytic converter you have. Mine has the H engine code and a single converter.
1st, Part# SUM-680022

I'm also confused as to which system to get. I did a comparison among 680022, 680023, 680024, and 680025. They all seem the same except 680024 excludes california models.
I'll probably go with the 680022 as it got alot of good reviews and someone put it on a 1982 camaro.

Re: Summit brand cat back exhaust?
Just got done talking to summit. As you noted, 680022 or 680023 are the ones to look at for our cars. In my case, since I have to modify the intermediate pipe either one will work.
I would suggest you use Summit's 24/7 chat feature in the customer service section of the website and give them your info. They're really helpful.

I will post a video as soon as it's on. Re: Summit brand cat back exhaust?
Here is a short video of my Camaro with the Summit 680022 kit. The car has a 355 now though. Headers are Summit shorties, Flowtech Y pipe, No Cat.
