If you add aftermarket headers and a CAT back will it void your factory or extended warrantee?

Your best bet is to go straight to the dealer and ask them. They will tell you what you can and what you can't add according to the warranty.

I have been asked this question quite a bit (i am a service advisor) and adding aftermarket components WILL NOT

 

WILL NOT void your warranty unless it is the aftermarket part that causes the stock component to fail.

 

If your vehicle is new enough to have a warranty, then I see no reason to swap cats at this point. New cats on today's vehicles are FAR better flowing then ones from days of yore. If I hacked them off my Z71 I'd be looking at maybe 10rwhp if I was lucky.

Shorty headers will not void warranty as long as they are CARB legal...besides the dealer would have to prove the headers caused the problem in question.
