Built for riders competing in AMA Supercross, AMA Motocross, and similar racing series, this system is engineered to help meet AMA/FIM sound regulations while supporting improved engine performance. The Ti-6 BC features titanium construction throughout the head pipe, mid pipe, canister, and end cap for a strong, lightweight exhaust solution.
