Yes. GM will send you a letter when you are reported by your Authorized GM Service Facility of your choosing...
I know one thing. I asked GM if I could install a C.A.I. and they said sure but you lose your engine warranty!!!

I called 6 dealers in my area about an aftermarket exhaust and was told the same thing. Yet the folks on here will troll and tell you otherwise.
What a dealership tells you and the truth are often in conflict.
 
@Jack Raccoon! I voided my engine warranty just for you.

Not bad for 1/3 of the price that GM wants. I did notice one of the hoses rubbing against the OEM cover and creating marks on the top right hand side. I’m sure overtime it’ll probably rupture. Did I route it correctly with the aftermarket piece if someone is able to check their car?
