Excessive noise levels threaten our riding areas. We’re all responsible for learning what we can do to make our bikes quieter, and respecting everyone who shares our natural resources. Next time you cross paths with someone enjoying backcountry recreation, make sure you’re running an FMF Q4 muffler, and turn it down a notch until you're in the clear. Working with organizations like the Blue Ribbon Coalition and ORBA, FMF is totally committed to reducing noise levels, and protecting our open backcountry.
TITANIUM Q4
Using all the experience, R&D and testing that went into the Q4, the next step was to create the ultimate off-road exhaust - the Titanium Q4. Sharing all the advances found in the Q4 and constructed from titanium, the Ti Q4 weighs less than most moto muffl ers and measures below 93dB on nearly all models tested (no more than 96dB on any model). The best way to describe the Ti Q4 would be “less is more” - less weight, less noise, more places to ride. This is the lightest, quietest and best performing spark arrested muffler made - period.
