i know that in order for them to void your warranty they have to prove it's the aftermarket part that caused it. but what are some of the possibilities that a cat back could void?

Thanks

ps... the serch does nothing...i tried serching... i hope there could be a better search function...

 

it could void your possibility of passing state inspection, and they could say that problems in your engine were caused by the installation of an exhaust, remember "beyond reasonable doubt" means different things to different people, and that's all your dealership has to prove to void your powertrain warranty.

but if you can pass emissions I say go for it, there's nothing it can really harm, unless free flowing gasses are a bad thing...

 

Who cares about what they say, just keep your stock exhaust and if something breaks stick it back on and take it in for warranty. They will never know if the stock exhaust is back on.

 

ditto. I would keep ALL stock parts, exhaust, intake, EVERYTHING!
