Vibrant SS Turbo FLEX Coupling with Interlock Liner 3in inlet/outlet x 4in long

* 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

* The inner braid liner protects the bellows from premature failure and is ideal for eliminating exhaust "whistle".

* 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
