PRC Brawler Heads
These really made a difference on my 13 Camaro SS. You can hear in the exhaust that they let the car breath more. The car runs and accelerates so much better now. I did have a leaky valve guide and TSP/PRC were being a pain to deal with. Michigan Motorsports stepped up and got me the parts and tool to fix the problem. They have excellent customer service and support. I will definitely deal with them in the future.
