Product Description

The Vibrant Performance 68944 4" Bellows Assembly with Solid Liner is a universal flexible coupling designed for use in custom exhaust systems. Made from high-quality 304 stainless steel with an electro-polished finish, this bellows assembly features a solid liner that promotes directional, smooth flow while absorbing vibration and thermal movement. This helps reduce stress on exhaust manifolds, downpipes, and other welded components, extending their service life in demanding applications.

With a 4.00" inlet/outlet diameter and 4.00" overall length, the 68944 is ideal for performance exhaust builds, turbo wastegate dump tubes, and custom fabrication projects that require vibration isolation and flexibility. Its universal fitment makes it suitable for many exhaust configurations, though welding and proper exhaust plumbing are required for installation.
