Issues arise. M5 F10 rear fits fine into my Msport bumper. However my chosen exhaust. Eissenman Race will not alight on the passenger side without what looks like some cutting/modifications. Problem is M5 valance openings are too inboard and Eissenman cans too big with not enough room to move/shift to the left inward without cutting hangers and trimming probably both heat shield and/or rear spare tire well. Dayum...decisions..decisions!
