Product Details

This FMF Racing Q4 S/A Muffler is built with a patented Power Bomb module, strategically placed in the header system. This design choice helps manage exhaust sonics, leading to an almost 10% increase in flow. The perforated core allows sound to escape into the steel wool packing, where it's absorbed, and then the gases expand and cool. Think of the Power Bomb as a pre-muffler; it adds more surface area for sound absorption, which helps reduce the overall sound output of your Yamaha YFZ450.

The construction focuses on both performance and sound management. By incorporating this advanced module, you get a noticeable improvement in how your exhaust system breathes, translating to better performance. The steel wool packing is key to dampening the sound, making this muffler a solid option for riders who want a bit more power without an overly loud exhaust note. It's designed to fit right onto your 2004-2009 or 2012-2015 Yamaha YFZ450, making installation straightforward.
