I just purchased a 09 wrx 5 door, and im planning to get myself a cobb turbo back exhaust system. I have no experience with mechanical stuff so im going to need to get it done by a professional. Where would be the best place to get it done at, or where do you guys get your cars fixed up at? Would a local Sears mechanical shop be good? I also live around Anaheim so if anyone can throw in a specific shop would be nice as well. Also is it required or recommended to get it tuned after getting it all installed?
