There's a review on the motordyne exhaust and art test pipes with a bunch of videos on here somewhere.
It sounds awesome when you get on the gas and doesn't drone as much as these other exhaust systems that don't have drone eliminator pipes. (from the review and just sound clips).
I have fast intentions exhaust and test pipes with supercharger and the drone can get annoying at 2-3K.
I am considering switching to motordyne because of drone. Motordyne sounds pretty raw. No hiss with the setup as well.
