Graves Slip-On Exhaust Yamaha R1 / R1M / R1S

Graves Motorsports Slip-On Exhaust Yamaha R1 / R1M / R1S

The Graves Slip-On Exhausts are designed for the rider seeking top of the line performance, fit, finish and value. This R1 exhaust was developed using the same technology that has powered Monster Energy Graves Yamaha rider Josh Hayes to 5 consecutive AMA Superbike championships.

Graves Everlast packing produces an exhaust note like no other and holds up longer to the extreme conditions of a high-revving motorcycle. Graves incorporates advanced welding processes to reduce oversized welds that can cause excessive heat buildup. A special pipe bending technique known as mandrel bending is used for all Graves exhausts to prevent wrinkles and ovalization of the exhaust pipes. All of this combined not only streamlines the appearance of the slip-on exhaust but saves significant weight over the stock exhaust!

Features:

• Diamond shaped muffler design that matches the R1's design
• Integrated exhaust hanger
• Aerospace grade titanium connecting pipe
• 14.4lbs lighter than stock
• Eliminates catalytic converter 
• Made in USA
