I just had a Random Technology down pipe/high flow cat. and a DynoMax exhaust kit installed on my '02 GTP. I ran it for about a day when the Service Engine light came on and has not gone off.
I assume this has to do with the change in emissions after the cat. My neighbor, a camaro guy, had similar problems when he removed his cat. Does anyone know if I can reset the computer to accept the new ranges as normal or do I need to get an O2 simulator? If I can reset it what is the procedure?
By the way, the exhaust sounds great and I can feel the difference. Thanks.
