The Pro Circuit Ti-6 Titanium Exhaust System is engineered for riders seeking improved performance, durability, and race-ready construction. Designed for select Yamaha four-stroke off-road and closed-course motorcycles, this complete exhaust system uses lightweight titanium throughout the head pipe, mid pipe, and canister. The system includes a carbon fiber end cap and is identified by manufacturer part number 0332345F.
Fitment: This exhaust system fits the 2023 Yamaha YZ450F, 2024 Yamaha YZ450F, 2024 Yamaha YZ450FX, 2025 Yamaha YZ450F, and 2025 Yamaha YZ450FX. Its removable United States Forest Service (USFS) approved spark arrestor allows riders to configure the system for off-road or closed-course use, while the design is intended to pass AMA and FIM sound regulations.
The Ti-6 system incorporates a machined aluminum muffler bracket for increased strength, an asymmetrical muffler configuration for greater packing volume, and a precision-machined mid-pipe-to-head-pipe joint for improved fit and leak resistance. TIG precision welding supports long-term durability, and the titanium end-cap construction delivers a professional racing appearance. Made in the USA, the Pro Circuit Ti-6 is a direct-fit performance exhaust solution for compatible Yamaha YZ450F and YZ450FX models.
