As the pioneer of quiet performance mufflers, we raised the bar again in ‘05 with the second generation of Q series mufflers - the Q2. Built from the ground up, the Q2 is a completely new design, engineered for maximum performance while maintaining a sound level at or near 93dB on most models. The Q2 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 Q2 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 Q2 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!
