FMF Beta RR350-480 4T 20-25 Quietcore 4 Hex Stainless Muffler
SKU:Description
FMF Q4 HEX MUFFLER
All FMF Exhausts are hand-built from start to finish in the United States, offering unsurpassed quality and integrity in every product produced in the Flying Machine Factory in southern California. Specializing in both 2 stroke and 4 stroke exhausts, FMF is the go-to exhaust brand for factory race teams around the world. As the official exhaust of the AMA world championships, you don't have to look very far to find an FMF system in the premier Supercross and motocross competitions on the planet.
The FMF Q4 Muffler range might not be quite as large as some of the other lineups from FMF, but that's not going to take away from the engineering masterpiece that the Q4 Muffler really is. When FMF first design the Q4 Muffler, they did it with one thing in mind - you don’t need to hear the power, you just need to feel it! The guys over at FMF are the leaders in high-performance quiet technology, and the Q4 Muffler is the next generation of quiet offroad exhausts. The technology and design behind the Q4 use intricate chambers, baffles, and proprietary multistage packing material to combine together flawlessly and make it one of the best performing quiet mufflers available on the market today. If you're heading out bush and don't want to wake up the entire countryside within a 50-kilometre radius, this could be the exhaust you're after.
The FMF Q4 has always been in a league of its’ own and our latest Q4 Hex is the most significant upgrade to date. You don’t need to settle for a plugged up moto muffler hampered by an insert when you can have a compliant muffler engineered for performance.
