you paid for a cat-back system.. and if you plan on doing header's, you'd not want that stock s-pipe

 

There was a local shop in Glendale that I used to go to. These guys were great and did good work for decent prices but that was 2-3 years ago and they've since closed. I don't recall the name of the place either. I'll try this forum Z28.COM! There is a section there where members in a specific area, AZ being ours, where people who live in that area can help you. Give me few and get some shops for you.
