Dubach DR.D Slip-On Exhaust Stainless Steel/Aluminum For Honda TRX400EX 1999-10

Features

• The unique attributes of the DR.D' 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
• Every DR.D Step System exhaust pipe 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' best manufacturing facilities
• 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 uses 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
• System type: Slip-on exhaust
