The Graves Motorsports Modular* Cat. Eliminator Slip-On exhaust system is a perfect mix of form and function. Eliminating the catalytic converter from the stock exhaust removes significant weight, reduces stored up exhaust heat, and increases the flow of exhaust gases. When all of these factors are combined it equals POWER. It features mandrel bent stainless steel tubing and carbon fiber silencers with tapered titanium conical outlets. An O2 bung (with plug) is provided for use with the stock Yamaha O2 sensor or the Dynojet® Auto Tune module which allows for live, closed-loop EFI tuning. Our "Everlast" packing produces an exhaust note like no other and holds up longer to the extreme conditions of a high revving motorcycle. This Cat. eliminator exhaust system delivers exactly what this revolutionary R1 deserves; big power, lasting durability, style, and sound. Exhaust system offers a weight savings of 9.2 lbs.
