I'v had some people tell me flat out that straight piping my truck will only void the exhaust warranty, but then iv had some tell me that it will void all my warranties, so i thought id ask the people that should really know, im wanting to straight pipe it pretty bad but i dont wanna do anything that will void my warranty. most of the people on here have said go for it but i dont know what to do

thanks a lot

Only the systems that any change directly affects, In this case, just the exhaust with 'your' truck.

Depends on the dealer, some will give you some grief about it if they are a crappy dealer. However any normal dealer should only not warranty the modified exhaust.
