I have a full TBR high mount system with the small oval cans. While riding the bike, they seem too loud at idle, and quite down a bit above 4000 rpms. Off the bike idle isn't obnoxious like damn near all Harley's, and aren't bad at all moving. So after hearing them off the bike, both standing by the road and following on another bike, I think they are reasonable enough. I've definately heard louder... I was nervous about the noise complaints I read about, but in person haven't found them too be "exactly" accurate.

The only noise complaints I've ever had was guys riding behind me at times when there isn't much change in rpms. They complained of the drone.

 

Jim, you're old and half deaf. They're loud. Come to think of it, I'm old and half deaf and they're loud.

 

My neighbors across the street say they can hear me start my bike every morning and I don't rev it. I just start it and start rolling down the street (It's a slight downhill for half the block. When I get to the bottom of the hill I shift to 2nd and navigate my way out of the neighborhood at 2K rpm. I leave at 5:00 am.

They say they don't mind but say they can definitely hear it. I have the high mount small C2 oval cans. I wear ear plugs all the way to work except for the last mile when I leave the 7 eleven. It sounds good but it is loud. Since I have been wearing ear plugs I wouldn't ride without them. They cut down the wind noise and I can hear my bike fine. I let a friend of mine ride it so I could hear it go thru the gears and it sounds awesome. And it has a nasty idle. The cruiser guys at work are jealous because their loud pipes don't have the same attitude.
