4.5" RACE-PRO SLIP-ON MUFFLER (17-20 MODELS)

• 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
• Feature 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
• Sold in pairs
• Raven black is slightly darker than the previous coating, providing the best finish possible
• Made in the U.S.A.
