Dunno what the problem is bro.

When I was working there I ran my car through and I passed no problem. 90 GT offroad h-pipe and borla catback with 150k miles on it. Guess mine is just a clean running car. When I worked there, they said changing the oil will help pass emissions testing. You really should have no prob with a 95gt and mac hi-flow cat hpipe. Try changing the oil I guess. May need it anyways.
