The subject says it all. Anyone know if puting on an aftermarket muffler voids your warrenty?

Some say that a performance part will only void your warrenty on parts that come after that part in the drive train.....so a performance cat would void everything after it........

....but lets get serious dealers are asshats. They will try to blame anything on a mod. But to answer your question a muffler should be cool.....just don't go into the dealership complaining about your muffler :)

muffler no

a muffler is a wearable part

just like brakes and wipers

In that case how about cuting off the resonator?

dunno...that may be more of a local code for you..not a dealer thing

screw the resonator
