I recently acquired a Georgia modified GT. It has full legth headers, Borla exhaust, H pipe and MAC cat converters attached to the headers. The headers have CO2 sensors and the H pipe has oxygen sensors. My problem is the the MAC catalytic converters are failing, cauisng the check engine light to come on. Where can I find replacements that attach directly to the header and can I replace the H pipe with an X pipe, since everyone says it is better.
