We have received and tested the first article of our undertail exhaust system for the Supersport family. I am quite pleased with the results! At idle and low rpm, the sound is quite low with a great bass rumble. Once on the throttle, the exhaust system is remarkably similar in sound to the Arrow full system for the Monster S*R family. Visuals to be presented in the near term... :) Now to have to go for a nice ride tomorrow.
