Vibrant Stainless Steel Flex Coupling with Inner Braid Liner 1.75" x 4"
The Vibrant Stainless Steel Flex Coupling with Inner Braid Liner is a high-quality exhaust component designed to add flexibility to performance and custom exhaust systems.
Measuring 1.75" in diameter with a 4" flex length, this coupling allows for movement between exhaust sections, reducing stress on pipes, mufflers, and manifolds.
The integrated inner braid liner protects the bellows from high-temperature exhaust gases and eliminates the common "whistling" noise often caused by high-velocity exhaust flow. Built from premium stainless steel, this flex coupling delivers durability, smooth flow, and a professional finish.
