Doug Dubach is proponent of good
practical power easy use on the track, in all conditions. We’ve never tested a DRD exhaust that hit super hard with an arm-jerking hit; instead,Doug aims for improvements that will actually help you lower your lap times. That said, we knew exactly what to expect when DRD’s Mark Tilley called us and offered up a Kawasaki KX450F that DRD had developed in conjunction with Simon Smart Body.
