It is not loud at all. I plan on posting a few sound clips. However it's tough to do ... they never sound the same. But that is V&H power dual and crusher mellow. It is in face not loud at all. I have had customer complain that they want it louder when done

Some I think get used to having a bike that is very loud so when you change the build it. They think sound level equals power.
I have the same system on my 124 love it. Its not going to impress any one in the parking lot, or scare children on the side walk. But it will make the power not upset the people next door or down the block.
I have tested other 2-1-2 and two into ones. Power wise I can get there with several systems sound wise well lets say it works extremely well.
