Outlet Diameter - 4" I.D.
Flex Length - 8"

- Vibrant flexible couplings are engineered to isolate vibration generated by your vehicle's engine, thereby relieving stress on the exhaust system.

- Flex couplings reduce premature cracking of manifolds and downpipes and help extend the life of other components.

- TurboFlex couplings feature an internal stainless steel interlock liner that facilitates smooth flow of high temperature exhaust gases. These flex are recommended for high performance (especially forced induction) applications.
