James Gaskets Exhaust Mounting Gasket Kit KWG2 For Buell XB9R Harley-Davidson

OVERVIEW

This James Gaskets Exhaust Mounting Gasket Kit eliminates flange leaks, restores proper exhaust routing pressure, and prevents fastener failure during scheduled maintenance or aftermarket header swaps. Constructed with tapered-profile compressed copper wire backed by high-density graphite plates, this sealing assembly provides a resilient thermal barrier that compresses evenly against aging mating surfaces. Intended as a direct replacement for worn factory seals on Sportster platforms and select chassis families, it simplifies heavy-duty exhaust repair without requiring specialized fabrication.

ENGINEERING & PERFORMANCE

The tapered profile actively distributes clamping force across irregular flange edges, stopping carbon tracking and vacuum leaks that disrupt backpressure management. Graphite-infused facing layers maintain structural integrity under extreme cyclic heating, preventing crumble-induced blowouts while minimizing surface scoring on exhaust ports. Heavy-duty flange nuts secure the assembly with corrosion-resistant threading to ensure stable torque retention through extended ride intervals and temperature fluctuations. This bolt-on design delivers OEM-style replacement performance while resisting thermal degradation and exhaust gas seepage over time.

WHY HARLEY RIDERS CHOOSE THIS

Riders install this James Gaskets kit when standard paper or single-layer seals fail to hold against frame flex, leading to rattling pipes and lost power. The dual-material gasket architecture adapts quickly to pitted or warped flanges, delivering a solid seal that protects downstream oxygen sensors and muffler baffle life. Graphite faces and copper wire cores survive repeated heat soak without shrinking, meaning fewer teardowns and consistent exhaust tone over time. The bundled heavy-duty flange nuts eliminate stripped threads and simplify bolting procedures, turning a messy gasket swap into a quick, reliable repair that keeps touring and cruiser models running quietly at highway speeds.
