Dr. D NS-4 Slip-On Exhaust

Product Description

The most popular exhaust in the DR.D line up. The DR.D SS/AL (Stainless Steel Tubing / Aluminum Can) is the exhaust chosen by more magazine test riders than any other; those who can ride with anything they want, choose DR.D. Lighter than the stock exhaust, the SS/AL features durable 304 stainless steel, TIG-welded construction and billet aluminum mounting directly on muffler can. Uniquely track tested to improve hit, delivery, and pulling power with substantial performance gains while reducing weight over the stock system. Welded construction, magnesium end cap, removable bolts (not rivets) at the inlet cap for easy repacking, and stepped perforated core (reduced heat) for increased durability set DR.D apart in construction, and on the track.

  • Performance improvements over stock system.
  • Features stainless steel mid pipe and aluminum muffler.
  • Lightweight magnesium end cap; riveted on for increased durability.
  • Welded construction for reduced weight.
  • Removable bolts at inlet cap for easy repacking.
  • Includes roll style packing; extends packing life.

Will this slip onto an existing DRD header pipe, a stock header pipe, or both?
I have an existing DRD silencer and header on my bike. The silencer cracked and I need to replace it. Will this slip right onto the existing DRD header? At the same time, can I also slip it onto an existing STOCK header?

Yes, the Slip-On will work with the header on your 2009 Kawasaki KX250F. At the same time, the Slip-On will work with the stock header.
