Features

• 4.5" diameter muffler bodies taper to 4" at the front
• 4.5" machined aluminum, thin-line tips
• 3" diameter muffler cores for superior performance
• 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
• 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
• Made in the U.S.A.
