I've got a 96 saturn sw1 with some bad exhaust. It has 2 O2 sensors ,one on the exhaust manifold and one after the cat. If I was to eliminate the cat would I have any bad affects?
Thanks Rick

check engine light from the rear O2, get a simulator, then u should be good..

also, expect alot of carbon out the exhaust

Why would there be carbon on the exhaust? The second O2 sensor only tells the computer the catalist isn't working. That wouldn't cause an unburnt fuel situation. BTW there's three on the system, O2s that is.

ive had 3 saturns, dont ask me why, they all did that when i put highflow/no cats on...
