Good luck on the getting a GM Performance Parts catback. They dont make one!
I'm going through my 06,07,08 GM Performance Parts and GM Accesories books and there is no exhaust for the Malibu. I wanted to get the same thing for my G/F's Bu SS when she got it, but there was no exhaust for it to be had. Mabey I'm wrong and am just mising it, but I dont think so.And until last year they did make one, same as a Borla with the GMPP logo.
