P0420 Code
My CEl is on for the P0420 code. After searching a little on the forum I see some mention to get an aftermarket y-pipe to eliminate the precats but I already have a Warpspeed Y-pipe and carsound hi-flow cat. What else could be causing the code? Is it an O2 sensor and if so which one do I replace? Thanks.
