Designed specifically for the Harley-Davidson Freewheeler. Although it is based on the Tri-Glide platform, the Freewheeler is at least three inches shorter, causing regular bagger mufflers to stick out three to four inches behind the rear panels.

When used with the stock head pipes, the mufflers are a simple bolt on

3.75-inch muffler bodies bell out at the end to four inches and are capped off with black powder-coated, machined aluminum race pro tips. Each tip is held in place with seven, 12-point bolts, which perfectly match the aggressive styling of the Freewheeler

The internal construction of the muffler bodies consists of 2.25-inch perforated constant velocity cores, wrapped in woven fiberglass that is protected by a fiberglass wrap; Providing outstanding performance with a deep thundering bass note
