brake Posted November 21, 2011 Report Share Posted November 21, 2011 I've never messed with stock exhausts on OBD-II cars - Do ours have 2x o2 sensors? one pre and one post catalyst? Reason I ask is my converter/pipe may very well be leaking and it would be much cheaper to replace with a length of straight pipe as opposed to a converter.....I put straight pipes on my Ford but it only has o2 sensors in the manifolds so anything downstream doesn't matter. what do you think? I don't particularly care about emissions; the car is inspected for another 2 years and I don't plan to have it inspected again I just can't really afford the cat/pipe and don't like carbon monoxide poisoning very much....at all really.

You could also run an o2 simulator in place of the sensor to keep the lite from coming on. Quote Link to comment Share on other sites More sharing options...
