Yeah the dealer i bought the car from was all about getting it off the floor and selling it and didn't tell me about the check engine light coming on. I got half way home form the dealer and the check engine light pops up. The cat went, and they tried getting me to pay for it. But we called GM and they called the dealer and yelled at them saying its covered under warranty. But yea, im looking to free up some exhaust flow so i can upgrade my pulley size to a 3.4. What do you guys think, down pipe, or headers.
