Dual Front-Pipe Exhaust Manifold Flange Gasket
TR6 Models

BritCar ServiceWhen replacing the manifold flange gasket, care should be exercised to ensure correct alignment of the gasket with the pipe openings when installing the manifold flange gasket on dual front-pipe exhaust systems. As the four bolt flange pattern is of equilateral design, the gasket can be installed 90 degrees out of position this creating an exhaust discharge restriction and subsequent loss of performance and power.
