08 g35 sedan exhaust ?
Hey guys I’m new to the forum.
Recently had a scan done on my car and it came back with error codes P0420 and P2A00 for the catalytic converters and A/F sensor.
My fuel economy has gone to sh*t and this is probably a dumb question, but would it be better to replace the cat or just replace the entire exhaust with a performance one?
Will I see my fuel economy improve as well?
