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 regular 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-inch muffler body morphs to 3.25-inches at the rear, and the RPT tip finishes off the rear
