Easy conversion to get a bit more rumble out of the otherwise modrate sound of the VH slash down slip on mufflers. these baffles add a nice thoaty sound and install in a matter of minutes. I wish they made them for the RSD Slip-ons as well.
These baffles are loud.......I put them inside an old pair of Vance & Hines that didn't have baffles and talk about hacking off the neighbors. I had to get rid of them maybe if they had fiberglass packing around them it would have been more tolerable. I had to drill another hole in the muffler to install the baffle that's why I gave fit and finish only two stars. Too too loud.....I must be getting old :)
