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. 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.
