I was just at the dealer on Friday, and got to hear this exhaust in person. It sounds excellent in person! They had two scramblers side-by-side. One was my brothers with the Termi slip-on that he was picking up, and the other was the Termi high race-line exhaust. They fired them both up so we could listen to them back to back. Both had the db killers removed. The slip-on is deeper, throatier, and a little louder, but they both sound fantastic.
Of the 4 people there, we all preferred the sound of the slip-on by a narrow margin, but I also think the high pipe sounds better with the baffle out than the slip-on does with the baffle in. The slip-on chirps with the baffle in, and I don't like the sound. Also, listening to Nimrandir's video, it sounds like the high exhaust has a similar chirp pitch as well with the baffle in.
