Titanium 4

The Titanium 4™ muffler offers the huge weight savings of titanium plus the performance characteristics we’ve developed through years of R&D work with Factory motocross teams. The Titanium 4™ is a lightweight titanium muffler canister mated up to a durable stainless steel Mig welded midpipe. A free flowing, straight core race muffler, the Titanium4™ is designed for closed course competition and features our versatile Hi-Flo modular end cap allowing easy changes to reshape the powerband, modify the sound output or add a Forestry approved spark arrestor. The Titanium 4™ is offered as a slip-on muffler fitting FMF as well as stock headers and for certain applications, a complete system – see part number list below.

The Titanium 4 racing exhaust system will give the ATV rider the huge weight savings of titanium with an overall horsepower and torque gain. All mufflers are available in a natural titanium finish or in a blue anodized finish. FMF’s Titanium 4 is fully tunable with modular end caps that allow for easy changes to shape the powerband of the machine and alter the sound level.
