The Ti-6 Titanium 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. The Ti-6 is ideal for any closed-course or off-road racer looking for improved performance, durability and a professional look. Although the Ti-6 will not pass FIM sound requirements seen in professional racing here in the states or in Europe, the Ti-6 will meet AMA amateur noise requirements, and comes equipped with a removable USFS approved spark arrestor making it easy for riders to alternate between off-road and closed-course racing.
