Graves Exhaust System Aprilia RS 660 / Tuono 660 2021-2026

Graves Motorsports Exhaust System Aprilia RS 660 / Tuono 660

The Graves Motorsports Exhaust System was designed for the rider seeking top of the line performance, fit, finish and value. This 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 exhaust systems but saves significant weight over the stock exhaust!

Features:

• Octagon shaped muffler design that matches the R1's design
• Full titanium headers and mid-pipes
• 18mm Lambda sensor receiver plug
• Integrated exhaust hanger
• Made in USA
