Problems with straight pipes..
So i was thinking about removing my cat and putting in a straight pipe.. But i was talking to a guy at an exhaust store. He said that the increased airflow would make my check engine light come on, and my performance would suffer... BUT he also said he had heard of a simulator that could trick the computer to think the cat was still there. Can anyone help me find this simulator? Or does anyone know anything about doin the straight pipe mod?

The rear O2 sensor will still pick up fuel in the exhaust because there is no cat there to burn them up, are you legally required to have a cat in your area?

yea a free flowing exhaust is good until a point. with straight pipes you can get too much flow which could cause you to lose some down low torque. i rode around the block with no muffler before i put my borla muffler on and man it was loud! pretty cool, cant lie.

even with the SC you still need some backpressure, now with turbos you want to eliminate as much pressure as possible because more flow= more boost= more power!
