Cometic Exhausts

5 products

Cometic exhaust gaskets for Harley-Davidson motorcycles are the detail that serious builders do not overlook, and they represent one of the most important sealing points on any V-twin exhaust system. While Cometic is best known for their Multi-Layer Steel head gaskets, their exhaust gasket range brings the same materials engineering to the header flange — the joint that has to withstand the most aggressive thermal cycling on the entire engine. Poorly sealing exhaust gaskets on a Harley-Davidson cause bluing, ticking, carbon tracking and ultimately damage to cylinder head surfaces, making quality here far more important than price. Cometic produces exhaust gaskets for Evolution, Twin Cam, Milwaukee-Eight and Sportster engines, and their reinforced materials deliver consistent crush and recovery across thousands of heat cycles. For anyone building a performance exhaust system, fitting high-flow headers or simply doing a proper job on a Softail or Touring service, Cometic exhaust gaskets close the loop on quality. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Cometic to give UK builders access to professional-grade sealing components. Browse the full Cometic Exhausts range below.
