• 304 stainless steel head and mid pipes
• USFS-approved removable screen-type spark arrestors
• Bolts to factory dual-exhaust mounting points

This is a 4-stroke exhaust. It is engineered for the 4-stroke engine architecture above and physically will not fit a 2-stroke bike. Verify your engine type before purchase.
