I was wondering, i am going to go install my megan 4-1 header, s-pipe, and cat back exhaust and leaving the stock cat on......will this void my warranty.....ive searched around and heard people talking about the pre-cat with the stock header.....(not forsure what there talking about)....all i want to know is if anyone is running/heard of this kind of exhaust system failing immessions.....

 

void warranty refers to

if THE AFTERMARTKET part damaged your car in anyway. then that part of the car's warranty is voided.

exmaple:
CAI, sucks in a lot of water during winter, took your car in to the dealer because it broke on you, they find out that you ran a CAI and that caused ur engine to break. the ENGINE warranty is now VOID, but thet sunroof and oter stuff on the car is still valid

 

what about inspection, would it pass?
