Are you talking about me
If so, I intentionally made mine louder. The OEM sidepipes on the Backdrafts (at least the 600 era) were very restrictive (also not that loud). I replaced them with the Classic Chambered exhaust, picked up HP and made it louder (I Likey alot). Try earplugs, I wear them all the time now. Not so much for the exhaust note but for the wind noise.
