All you Need to Know About Exhaust Flange Kits for Motorcycles
What is an Exhaust Flange? Unlike passenger cars and trucks that connect exhaust pipes directly to the engine via the exhaust manifold, motorcycles, racing cars, and ATVs use exhaust flange kits. These kits replace the exhaust manifold, which would otherwise reduce engine efficiency by creating a back pressure that forces the engine to use more power to counteract the pressure. Laser cut flanges are typically individual pipes used to connect the exhaust outlets to the cylinders. The pipes converge right before they reach the muffler. The absence of an exhaust manifold makes it necessary to hold the exhaust header in its place with the help of an exhaust flange instead.

Types of Exhaust Flanges There are different types of exhaust flanges used in motorcycles. The most common of the flanges work with exhaust pipes with flared ends to hold the flange in place. Another design option is the ball type, where the exhaust head bulges near the tailpipe, with the bulge portion supporting the exhaust flanges.

Gasket Requirement Standard laser cut exhaust flanges require a gasket to function properly. This is because the flange acts as a seal at the end of the header pipe and needs a gasket for an opening. However, ball type exhaust flanges don’t need gaskets as the bulge portion of the exhaust header itself creates a seal with the tapered part of an exhaust flange.

Materials used for Gasket Hardware laser cut flanges operate under high temperatures. Hence, the gaskets used are made of several soft metals that are mixed with normal gasket material like paper (treated to resist heat without igniting at high temperatures). A gasket can take on different forms as well, including steel rings, crush rings, steel mesh rings, and tapered rings.
