FMF KTM Q4 Exhaust

As the pioneer of quiet performance mufflers, FMF raised the bar again in '07 with the second generation of Q series mufflers - the Q4. Built from the ground up, the Q4 is a completely new design, engineered for maximum performance while maintaining a sound level at or near 93dB on most models. The Q4 incorporates Factory Forward Engineering to move the muffler closer - centralizing the mass for improved handling characteristics. The new Hi-Flo formed end cap reduces weight and is less prone to damage. The Q4 has an anodized aluminum canister and is lighter and quieter than the original Q. All three models utilize a maintenance free USFS approved turbine type spark arrestor so there is no screen to clean or burn out. With their free flowing internal baffles and chambers, advanced sound-absorbing materials and now reduced weight, the Q4 is the market leader for low sound/high performance. Less sound equals more ground. Be part of the solution and take the noise out of riding, not the fun!

The new Q4 provides more power than the original groundbreaking Q & Q2 plus now it is even quieter! The 'Q4' uses internal baffles, chambers and space age sound absorbing materials to accelerate exhaust flow fo less noise - and more power! The internal 'bullet' spark arrestor and performance flow end cap help, reduce sound AND enhance the exhaust flow dynamics. Add in the aluminium oval can and stainless steel maid pipe and you've got the ultimate lightweight all legal, low maintenance 4-stroke muffler. The new 'Q4' focued off road quiet power.
