Installation is a Snap:
All systems use factory mounting locations providing stability and hassle-free installation.
High quality OE style band clamps are used for a complete 360 degree sealing surface.
A muffler delete-pipe is used for a true race-inspired sound and maximum flow.
OE style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The Bayonet tip holds the hanger bushing in place for an OE style fit that does not change with time.
