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.
