Cometic EX657 Spiral Wound Exhaust Gasket - 4 Pack

The spiral-wound construction of these Cometic EX657 exhaust gaskets uses a stainless steel outer guide and inner ring with a graphite filler. This design is built to handle the high temperatures and pressures found in your Yamaha FJ1100 or FJ1200's exhaust system, helping to prevent leaks between the exhaust manifold and the headpipe. A proper seal here is important for maintaining engine performance and keeping exhaust fumes contained.

This 4-pack gives you enough gaskets for multiple applications or replacements. The stainless steel outer guide helps with alignment during installation and protects the filler material from damage. These gaskets are designed to create a strong, reliable seal that can withstand the vibrations and thermal cycling typical of motorcycle exhaust systems.
