I appreciate all the replies. Thank you. My dealer said any GMPP parts installed by the Dealer will be fully covered under warranty..but, I can see where they may then say that the part caused something else to fail and that isn't covered....
But, pardon me, I'm still confused why would GMPP offer a catback and cam for this car, but then say that it caused other failures?.
Cancelled the 2010 SS/RS (for now) and bought this instead (2009 Harley FLHX)
