Type 25 Exhaust Gasket (55mm Triangle) - Waterboxer

This replacement exhaust gasket is used to seal a three-bolt triangular exhaust flange, providing a gas-tight joint between exhaust components. With a 55mm internal diameter, it is commonly found on a wide range of Volkswagen and Porsche exhaust systems across multiple generations and engine sizes.

A sound gasket at this joint is essential to prevent exhaust leaks, reduce noise, and maintain correct exhaust flow and back pressure. Over time, heat cycling and vibration can cause exhaust gaskets to fail, leading to blowing joints, rattles, and potential MOT failures. This gasket is designed as a direct replacement, manufactured to the correct shape and dimensions for reliable sealing.
