Exhaust gaskets

An exhaust manifold, interference pipe or muffler must be tight at the connection and joint points, not only because of the noise development, which the exhaust is actually supposed to dampen, but also because of the performance. If the system leaks at these points, the mixture formation on the intake side can be influenced: The result is poorer performance.

Not all connection points on Harley-Davidson exhaust systems had seals ex works. But if a gasket is needed, you can get it here at W&W Cycles, the specialists for gaskets and sealing rings for vintage treasures: Genuine James Gaskets and Competition Distributing.
