- 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
