Tri-oval-shaped muffler rear seamlessly transforms into 4" round front

5" wide, 4" tall thin-line aluminum tip
3" core for superior performance
Acoustical engineering developments allow an incredibly deep sound because of intense, class-leading resonance absorption and prevention
Feature 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.
