If you’re looking to get the most sound out of your new Softail, these are for you. Mufflers make use of all of the high-tech features of Cobra’s other three-inch slip-on mufflers, including two-inch constant velocity cores for exceptional sound and performance, as well as the bonded e-glass and stainless steel mesh. The constant velocity cores are designed specifically for the Milwaukee Eight engine platform, to provide the best sound and performance. The 3″ muffler body morphs to 3.25″ at the rear, and instead of using a billet aluminum tip there is a rolled steel tip and separate inner flared tip.
