Graves Cat Eliminator Slip-On Exhaust for Yamaha R1

The Graves Slip-On Exhausts are designed for the rider seeking top of the line performance, fit, finish and value. This R1 exhaust system 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!
