The Pro Circuit Ti-6 Titanium Exhaust System with Carbon Cap is engineered for riders seeking improved performance, durability, and professional-grade construction on off-road and closed-course Honda CRF450 models. Constructed from titanium throughout the head pipe, mid pipe, and canister, this exhaust system helps improve power while reducing weight compared with conventional exhaust designs. The system includes a titanium end cap and a removable United States Forest Service (USFS)-approved spark arrestor, allowing riders to switch between off-road and closed-course use.
Designed for a precise fit, the Pro Circuit Ti-6 features a machined mid-pipe-to-head-pipe joint for a secure, leak-resistant connection. TIG precision welding supports long-term durability, while the machined aluminum muffler bracket provides increased strength. The asymmetrical muffler configuration increases packing volume to support consistent performance and sound control. The system is designed to pass AMA and FIM sound regulations and is made in the USA.
This Pro Circuit exhaust system fits 2021 Honda CRF450RX, 2021 Honda CRF450R Works Edition, 2021 Honda CRF450R, 2022 Honda CRF450R, 2022 Honda CRF450R Works Edition, 2022 Honda CRF450RX, 2023 Honda CRF450R, 2023 Honda CRF450R Works Edition, 2023 Honda CRF450RX, and 2024 Honda CRF450R models.
