The Ti-6 Titanium Dual Exhaust System is designed to improve performance and is constructed of titanium throughout the head pipe, mid pipe, and canister while the end-cap is constructed of carbon fiber. Improving power where the Ti-5 showed weak points, and based on customer feedback, a distinctive sound was also created to try and accommodate the current motorcycle rider. Although the Ti-6 will not pass FIM sound requirements seen in professional racing here in the states or in Europe, it is still the ideal system for any rider or racer looking for improved performance, durability and a professional look. In addition to all of these features, the Ti-6 comes with a removable U.S.F.S.-approved spark arrestor making it easy for riders to alternate between off-road and closed course racing.
