FMF Racing Honda CRF450R/RX 21-26 Q4 S/A Muffler

A 4-Stroke header system that incorporates FMF's patented Power Bomb module at a precise location in the initial stage of the header system; by positioning the "Bomb" at this key point, the expansion and contraction of exhaust sonics through the system resulting in a flow increase of nearly 10%. The surface of the perforated core lets the sound exit into the absorbing material (steel wool packing) and then allows the air to expand, cool and ramp back up at higher air pressures (RPMs). The Power Bomb is a "pre-muffler" of sorts, which helps to lower the bike's sound output because it provides more sound-absorbing surface area to allow the exhaust gases to become absorbed.

Upgrade your Honda CRF450R or RX with the FMF Racing Power Bomb Header System, designed specifically for models from 2021 to 2023. This 4-stroke header features FMF's patented Power Bomb module strategically integrated into the initial stage of the header to optimize exhaust flow and performance. The precise placement of the Power Bomb results in nearly a 10% increase in exhaust flow, which can translate to improved acceleration and power delivery. Constructed with a perforated core, the header allows sound waves to exit into a steel wool packing material, which helps dampen noise and cool the exhaust gases. This process not only enhances exhaust efficiency but also reduces sound output, making your ride quieter without sacrificing performance. The design acts as a pre-muffler, providing additional sound absorption and contributing to a smoother, more refined exhaust note. Built with durability and compliance in mind, this header system is EPA compliant and suitable for various Honda CRF450 models, including the R, RX, RL, RWE, and R-S variants. Its robust construction ensures long-lasting performance under demanding riding conditions, while the straightforward installation makes it a popular choice for riders seeking increased power and a quieter exhaust system. Whether you're racing or trail riding, the FMF Racing Honda CRF450R/RX 21-26 Power Bomb Header System is engineered to enhance your motorcycle's exhaust efficiency while maintaining a compliant and reliable performance profile. Suitable for enthusiasts looking to improve their bike’s sound and power output, this system provides a significant upgrade over stock headers with minimal effort. The header’s design emphasizes performance, durability, and sound management, making it an essential component for serious riders aiming to maximize their Honda CRF450’s capabilities.
