DRD 4-Stroke ATV Exhaust

  • 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 mid and top ranges. Dyno tests show a 3.6 horsepower increase at peak.
  • Every DR.D Step System exhaust is manufactured from high-quality, 304-series stainless steel. Each step in the exhaust pipe is achieved via a precision machined ring that not only adds to the performance, but gives the DR.D pipe a distinctive look. The complete system is purged and welded in one of the nation's best manufacturing facilities.
  • The muffler is constructed out of 6063 aluminum to lower the overall�weight of the system and provide an aggresive, but pleasant, exhaust note. DR.D used a "pillow" exhaust packing method to gaurantee U.S.F.S. spark arrestor to allow you to use your ATV in a wide range of locales.
