DRD Exhausts Full NS-4 System Stainless/Aluminium


RMZ250 2010 - 2014 / RMZ450 2008 - 2014

Every DR.D exhaust is built, developed, and tested by Doug Dubach. DR.D pours more time into track testing, with more experience, than any other company. A former Factory Supercross rider and career test rider, Dubach is widely considered ‘the greatest test rider in the sport’. DR.D exhaust performance is unequalled; while others simply search for peak horsepower on a dyno, Dubach spends hours riding stock bikes to understand where each needs improved power character and/or more power! The DR.D R&D Test Centre in Warner Springs, California is Dubach’s labor of love; it houses our engineering team, advanced CAD/CAM technologies, Data Acquisition, Dyno Jet 500 and most importantly, three (3) unique test tracks.

DR.D exhausts are not mass produced, each exhaust is unique and each has been developed on the track to best improve the bikes power character. You won’t find ‘universal’ components, such as heavy springs and gaskets, in our construction because cutting corners, on the track or in production, is never beneficial.

Take it from the man who has spent more testing time on a Honda, Suzuki, KTM, Kawasaki, and Yamaha than all others combined. If it passes Dubach’s test, it will pass yours.


Stainless Stee/Aluminium

The most popular exhaust in the DR.D line up. The DR.D SS/AL( Stainless Steel Tubing/Aluminium 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 aluminium 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 Header, Mid Pipe, and Aluminium

• 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
