These novel 4-inch muffler bodies feature advanced acoustical tuning technologies for a deep rumbling sounds. The 4-inch round muffler front expands just aft of the steel clam shell clamp to 4.5-inches diameter.
- Bodies taper to 4" round at the front.
- 4.5" machined aluminum thin line black tips are held in place with seven stainless steel, 12-point bolts.
- Features satin black laser-cut steel straps that tightly encircle the mufflers with built-in mounting straps.
- 3" cores for superior performance.
- The frequency and location of the perforation patterns in the cores creates significant sound scattering in the mid frequencies, which helps to enhance the low frequency tones.
- Acoustical engineering developments allow an incredibly deep sound because of intense, class-leading resonance absorption and prevention.
- Use proprietary materials with specific acoustical dampening and thermal insulation properties.
- New Raven black is slightly darker than the standard black finish.
- Sold in pairs.
- Limited lifetime warranty.
- Made in the U.S.A.
