Simple Installation:
This system uses factory mounting locations providing stability and hassle-free installation.

OE Fit:
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.
