Description
A leaking muffler junction gasket compromises both performance and aesthetics on your Big Twin—allowing exhaust gases to escape where they shouldn’t and creating unwanted noise. This OEM-specification gasket from JAMES seals the critical junction between your muffler and exhaust system, restoring proper back-pressure and eliminating leaks that degrade horsepower and fuel efficiency. As a wear item that experiences thermal cycling and vibration, replacing your junction gasket during routine maintenance prevents costly exhaust damage and keeps your engine running at peak efficiency.
