Product Details

This FMF Racing Powercore 4 muffler is made specifically for your 2004 Honda CRF450R. It's designed to give you a noticeable boost in horsepower and torque across the entire range of your engine's power band, making it useful for any kind of riding you do.

The muffler itself is constructed from aluminum, which keeps the weight down while still being strong. It features durable stainless steel components, including the Hi-Flo end caps, offering a good balance of performance and toughness. This is a slip-on muffler, meaning it's designed to fit right onto your existing exhaust system without major modifications. A removable spark arrestor is also included, which is important for trail riding to prevent sparks from escaping.
