I think I found another solution to turning off the check engine light after aftermarket exhaust. I put 93 octane in my 2000gt and it shut off the light. Has anyone else tried this?

No, I have a MAC X pipe running into the MAC catback. It removes the sensors, causing the light to come on. It is funny how people overlook the old gas cap. My girlfriend's car had the light come on and just before she took it to the shop I tightened the gas cap. Sure enough it turned off!:p
