Also the M Performance does not provide any performance gains. It is strictly a sound improvement upgrade. Hence why I advise people to skip the M Performance exhaust and go with our Sport Cat Downpipe. It's cheaper, CEL free, and provides both performance gains and sound improvement. Check it out!
