Graves' precise engineering develops precision products that are designed to outlook, outperform and outlast the competition. Graves Exhaust systems are designed for the elite rider seeking top of the line performance, fit, finish and value. This exhaust system was developed using the same technology that has powered the Graves Racing Team to 31 Professional AMA National Championships including 9 Superbike Championship titles, 3 X-Games Championships, 2 SuperMoto Championships and 3 Pro Side x Side titles. Mandrel-bent titanium tubing.

• Titanium 200mm silencer with Titanium tapered conical end cap.
• Hand crafted in the U.S.A.

Graves Motorsports did not allow compromises in the development of this system. Material diameters and lengths are optimized for maximum power output throughout the throttle and RPM range. Combined with Graves custom FTECU map, this system produces huge mid-range and top horsepower gains. This tune also removes any computer error codes the bike will have when installing a competition exhaust system.

Graves Motorsports uses the same 1.00 mm thick wall high-heat titanium tubing used on their Superbikes. This material is designed specially for maximum durability and oxidation resistance up to 800 Celsius / 1472 Fahrenheit. It is designed to live at almost twice the temperature of normal Grade 2 titanium. The tubes are precision bent and cut with the latest equipment available. The tubing is then welded in fixtures designed so that repeatability is second to none. The collector joints utilize machined titanium receivers for a perfect fit every time. The spring tabs are made from 4 mm thick titanium wire for long life.

• Titanium 200mm Diamond Shaped Silencer Design with tapered deep draw entrance and exit caps designed to match the R1's body line.
• Strapless silencer design mounts without the use of strap bands around the can using a tap mounted bracket that's integrated into the can; this design not only streamlines looks of your bike and saves weight.
• Constructed from aerospace-grade high-heat titanium alloys.
• Four braced Lambda sensors (one on each down tube) for cylinder specific tuning.
• Advanced welding process showcases laser perfection welds.
• Long tapers with precision fitment and "butt" welds.
• Flanges are made from 7075 T651 hard anodized aluminum.
• Titanium silencer bands.
• Optimized Graves spec flash tune maps on the FTEcu database for tuning.
• Note: REQUIRES KIT OIL PAN - will NOT mount to stock bike.
