I have tried looking through the search for a simple answer to this question, but have failed miserably.
I have been thinking about replacing them with aftermarket (flowmaster) but didn't know if I needed to replace all 3 or just get the two that attach to the headers?
Additionally, will aftermarket cats throw a code with the o2 sensors? Or?
