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, FMF’s original titanium muffler, bolt on performance for any 4-stroke.  FEEL THE POWER!
