I have the V&H 3" Twin Slash Cut round slip-on and really love the sound though I'd prefer to try and tone it down some. I have read others doing this by installing the oem quiet baffles so I ordered a set to try it out. Can you install these with the slipons on the bike or am I better off removing them? I have read that these can be a bear to install so any suggestions are greatly appreciated. Any specific tools make this easier? Exhaust has only been on the bike for 1500 miles or so so hoping the installed baffles slide right out .
