I bought a badmab header and a zzp down pipe with hf cat.I installed it a few days ago and I went to the track yesterday I blew a gasket in the exhaust somewhere but I didnt have time to check it so when I went to work the car drove fine.as I got out of work I started the car and drove 50 ft and it sputtered amd stalled and now wont start .I checked the codes for cel and they were 0068 and the other was rich in one of sensors/banks

If you have an exhaust leak from a blown exhaust gasket, i would speculate that its drawing in fresh air from the outside, mixing with the exhaust causeing the O2 sensor to think you are running lean and thus compensateing your fuel trims to go rich.
