The car that I just bought does not have any catalytic converters on it. I can register it as a vintage if I want but I do plan on driving it whenever I can so I want to be able to register it normally. Just wondering if any of you have any good exhaust shops you like to work with, preferably in salt lake county, a plus if close to West Jordan. I also need some things fixed with the computer, it's a stock gm computer for a ls3, if anyone tunes or knows a good person for tuning the computers, please let me know. I need the speedo fixed, assume the tire size and gear ratio needs to be changed in the computer, and need to see if any codes have happened recently, no check engine light.
