2" Rush Baffles fit stock Harley slip-ons. Fits all stock Harley and Screamin' Eagle straight-cut, slash down or slash out slip-on mufflers (will fit Fat Boy/Lo, Cross Bones, Softail Standard/Custom/Deluxe/Springer/Slim/S, Night Train, Rocker/C, Breakout, Heritage, Blackline, Deuce, Fat Bob & Wide Glide...won't fit tapered mufflers). Baffles have a straight through design and come with fiberglass wrap. Very easy to install...they rumble even at idle. Not too loud but improve the stock sound to a deeper, richer note. Sound better than the Screamin' Eagle slip-ons. $120.
