Twisted Choppers Stainless Exhaust Flange Kit for Harley-Davidson Evolution Twin Cam M8
Swapping to a single-piece 2-into-1 exhaust system goes much smoother when the flanges are designed for it. This Twisted Choppers stainless exhaust flange kit uses a slimmer profile than the thick factory flange, giving the hardware clearance it needs to install cleanly on Big Twin and Sportster engines across every major platform from Evolution through Milwaukee-Eight.
