Will a New cat back exhaust void my warranty?
Looking to possibly get an after market exhaust other than the m performance, but I'm worried about voiding the warranty.
Appreciate any feedback you all can give me - thanks! |

I'd say it will depend on your dealer. The dealers I've worked with generally will not make a fuss about an aftermarket exhaust or intake, for instance - but not all are the same way. Best advice is talk to your SA about it.
That said, I have the MPE (port-installed) and it sounds great. Cat-back on an N55 (single pipe) probably won't do much better, and you run the risk of "highway drone", which can be very annoying.

Honestly doing a down pipe is your biggest gain and sound improvement (30 hp). You will get cell lights so you'll need JB4 to clear them but unfortunately you'll also gain a shit load of power (60 hp plus). You can also pull this off for under a $1000. Your but dyno will feel the difference. But watch out there's a lot of experienced ( 50 years plus) people on here that will tell you different.
