Drd Atv Exhaust Yamaha Yfm250 Raptor 2008-2012 - Head Pipe

The unique attributes of the DR.D’s step system is that it allows for a more efficient intake stroke. It does this by resisting the reflective exhaust pulse during the intake/exhaust overlap. In plain language, the carefully tuned steps in the system allow for a lower net cylinder pressure, which gives a crisper throttle response from bottom to top. The key advantage of the Step System is improved low end response with substantial gain in the mid and top ranges. Dyno tests show a 3.6 horsepower increase at peak.

The muffler is constructed out of 6063 aluminum to lower the overall weight of the system and provide an aggressive, but pleasant, exhaust note. DR.D used a “pillow” exhaust packing method to guarantee U.S.F.S. spark arrestor to allow you to use your ATV in a wide range of locales.
