Has anyone replaced or completely removed there catlylatic converters, I've been told this will allow the exhaust too breather better, improve on MPG & Performance. I have also been warned it may interfer with the O2 sensor which may screw up the computer output to the engine.
I had a cat. malfunction and saw performance and gas economy suffer greatly! On a side note, don't forget there is a 80K mile warranty on the emissions systems!
I have a aftermarket cat I purchased and never installed. The Shop was afraid it would confuse the oxygen sensors and make the check enginge light stay on.
