Vibrant SS Flex Coupling with Inner Braid Liner 1.75in inlet/outlet x 4in flex length

This Vibrant flex coupling is made from T304 stainless steel and features an inner braid liner. This liner is key because it protects the bellows from high temperatures and helps to stop that annoying exhaust whistle that can happen with high-velocity exhaust flow. It’s a well-built part designed to help isolate the vibration generated by your engine, which can reduce the chances of premature cracking in your exhaust manifolds or downpipes.

The 1.75-inch inlet and outlet are a common size for custom exhaust fabrication, and the 4-inch flex length gives you some room to work with. Vibrant recommends this flex coupling for naturally aspirated applications. It’s a solid option for custom exhaust builds where you need a bit of flexibility and want to keep the exhaust note clean.
