Pro Circuit's Ti-6 Pro Titanium Exhaust System was created for professional racers competing in a series such as AMA Supercross or AMA Motocross to ensure they pass AMA/FIM sound regulations. The Ti-6 Pro Titanium Exhaust System is constructed of titanium throughout the head pipe, mid pipe, and canister while the end-cap is carbon fiber. The Ti-6 Pro is the next generation of professional level race exhausts. The Ti-6 Pro is a full race system intended for closed-course racing only.
