DRC Exhaust Joint Gasket 45 x 38 x 30mm

The DRC Exhaust Joint Gasket is a high-density replacement seal for the slip-joint between exhaust sections. Measuring 45mm outer diameter, 38mm inner diameter and 30mm wide, it re-seals the header-to-pipe connection so exhaust gas stays in the system and outside air stays out.

A crushed or blown joint gasket is a common cause of lost performance and popping on deceleration, so this is a routine service item for riders pulling the pipe off for maintenance, top-end work or a pipe swap. Check the outer diameter, inner diameter and width against the gasket you are replacing before ordering, as exhaust joint sizes vary between models.

• 45mm outer diameter x 38mm inner diameter x 30mm wide
• High-density construction for an airtight exhaust joint seal
• Seals the slip-joint between exhaust pipe sections
• Helps prevent power-robbing exhaust leaks
• Blocks oxygen entering the system, reducing popping on deceleration
• Routine replacement item whenever the exhaust joint is separated

Confirm fitment before installing: measure the gasket you are replacing and check it against 45mm OD, 38mm ID and 30mm width.
Treat exhaust joint gaskets as single-use — fit a new one every time the joint is separated, as the old gasket has already compressed to shape.
Scrape and wire-brush all old gasket material, carbon and rust from the header spigot and the mating pipe before fitting, so the new gasket seats squarely.
Fit the gasket dry and push it fully home into the joint; do not use silicone or RTV sealant unless your service manual specifically calls for it.
Refit springs, clamps or bolts evenly and tighten to the manufacturer's torque specification — over-tightening can crush or distort the gasket.
Run the engine to operating temperature, let it cool, then re-check clamp or spring tension after the first ride.
Check for leaks by looking for soot streaks or black staining around the joint and listening for a ticking or blowing sound under load.
Store spare gaskets flat in their packaging in a dry place; the material is brittle and can chip or crack if dropped or compressed.
