Bolt 2-Stroke Pipe Kits provide all the sealing and retention hardware needed to correctly fit and seal your expansion chamber — including pipe O-rings, pipe-to-silencer coupler and exhaust springs — matched to your specific two-stroke model.

Two-stroke expansion chambers rely on correctly-fitted O-rings and springs to maintain a gas-tight seal between the pipe, engine and silencer. Leaking or damaged seals cause power loss, increased noise and potential overheating, while broken or stretched springs allow the pipe to rattle and work loose. A Bolt kit replaces all these wear items in one go, restoring a proper, leak-free exhaust seal.

Features:

• Complete kit — O-rings, pipe-to-silencer coupler and exhaust springs
• Model-specific for correct fitment to your expansion chamber
• Restores gas-tight sealing between pipe, engine and silencer
• Eliminates power loss and noise from exhaust leaks
• Meets or exceeds OEM specifications

Please confirm compatibility with your year, make and model before ordering.
