I installed Akra SS, but tried yesterday Remus, both with the baffle in. The Remus sounds nice but is a way too loud for me. 20 years ago, maybe... Akra has more of a discreet beat and is better suitable for longer trips, at least for me. By the way, since some members, me included asked whether Remus can be fitted with side racks, the answer is - yes. I have personally, the Hepco ones.
