Headers question

RE: Headers question
yeah i read on some other forum that there not sure which warranty it would void. I tried asking the dealer but they just str8 out told me "it will void your WHOLE WARRANTY" which i know is a lie just so they dont have to do warranty work. I was thinking it would prolly just void the exhaust system ?
