For the rider that is looking for something a little different, the stainless steel Low Boy Drag exhaust. This system features mandrel bent stainless tubing, billet aluminum flanges, and our full carbon fiber side exit silencer. It is extremely light yet offers the amazing horsepower increases Graves is known for. 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 reving motorcycle. This full exhaust system delivers exactly what this revolutionary R1 deserves; big power, lasting durability, style, and sound. System gives an overall weight savings of 15 lbs. compared to stock exhaust system.
