Collection: FMF Racing
FMF Racing is the world's leading manufacturer of high-performance exhaust systems for powersports. Founded in 1973, FMF (Flying Machine Fabrication) has spent over 50 years engineering exhaust systems that deliver real, measurable power gains for ATV, UTV, and snowmobile riders. Their lineup spans complete exhaust systems, slip-on mufflers, exhaust headers, heat shields, spark arrestors, packing kits, and rebuild hardware — every component engineered to maximize torque and horsepower while maintaining durability in demanding off-road conditions. Legendary product lines like the Q4 slip-on muffler, Powerbomb header, Hi-Flo HDR, Turbinecore 2 silencer, and Titanium series are trusted by riders at every level from weekend trail riders to competitive racers.
At JKL Offroad, we stock FMF Racing's full catalog of ATV, UTV, and snowmobile exhaust components. Whether you're bolting a Q4 onto a Yamaha Banshee, fitting a Powerbomb header to a Honda TRX450R, running a Turbinecore on a Kawasaki KFX, or upgrading the exhaust packing on your favorite trail machine, you'll find the right FMF part here. Every product ships directly with the quality and fitment FMF has refined over decades of motorsport engineering.
