How's the RSR sounds on the highway, specifically about 75 in 5th gear? I've got a Thermal right now and it sounds great (nice deep sound) but it tends to resonate on the highway and can become annoying if your trying to have a conversation (I have their stealth/silencer version). I was thinking of buying an WS just to have something quieter but I never bought one. I remember all the talk about RSR back when I first bought my Honda, but nobody I know ever had one. Seeya.
