4-STROKE SLIP-ON EXHAUST
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 per-
formance 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 Center 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.
