The Pro Circuit Ti-6 Titanium Exhaust System is engineered for riders seeking improved performance, durable construction, and a professional race-ready appearance. Designed specifically to fit the 2026 Yamaha YZ450F, this complete exhaust system includes the head pipe, mid pipe, and canister, all constructed from lightweight titanium. The system is well suited for off-road and closed-course racing applications.
The Ti-6 system includes a carbon end cap and a removable United States Forest Service (USFS)-approved spark arrestor, allowing riders to configure the exhaust for applicable off-road or closed-course use. Its asymmetrical muffler design provides increased packing volume, while the machined aluminum muffler bracket adds strength and durability. A precision-machined mid-pipe-to-head-pipe joint promotes a secure, leak-resistant fit.
Pro Circuit uses TIG precision welding throughout the system to support consistent construction and long-term performance. The exhaust is designed to pass AMA and FIM sound regulations and is made in the USA. Manufacturer and vendor part number 0332645F identifies this Pro Circuit Ti-6 system for the 2026 Yamaha YZ450F.
