Product Details
The FMF Racing Q4 S/A Muffler is built with a patented Power Bomb module, strategically placed in the header system. This design choice is key because it helps manage exhaust sonics, leading to an almost 10% increase in flow. The perforated core inside the muffler allows sound waves to pass through to the steel wool packing, where they are absorbed. This expansion and contraction process also helps to cool the gases and increase air pressure as RPMs rise.
This Power Bomb module acts as a pre-muffler, significantly reducing the bike's overall sound output by providing a larger surface area for exhaust gases to be absorbed. This well-built muffler is designed to fit specific Yamaha models, offering an improved exhaust note and better performance without excessive noise.
