At the top of nearly every four-stroke exhaust shootout, the Dr. D system stands second-to-none in research and development. No one has more hours in the testing saddle than Doug Dubach.

Expect up to a 3 - 5 horsepower gain and up to a 50% weight savings.
Each step in the exhaust pipe is achieved via a precision machined ring that not only adds to the performance but gives the Dr. D pipe a distinctive look.
The USFS spark arrestor version comes standard with a removable spark arrestor screen.
Stainless steel complete exhaust.
Includes head pipe.
Note: WR models require mounting kit (sold separately).

A: Most aftermarket systems sound pretty much the same. Some have a deep sound and some, after a few miles, have a raspy sound. Some will have a different tone and even the same exhaust system can sound differently on different models of motorcycles. In general most systems are around 92 to 98db's.
If you run your rpm up to the rev limiter the db's may go as high as 100 to 102+db's.
