0312145F - Pro Circuit Ti-6 Exhaust System - Honda CRF450R 2021-2024

Features: TI-6 TITANIUM EXHAUST SYSTEM. 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.. It does NOT pass regulations but didn't pass them before 2024 either.
