The matte titanium finish on the aluminum tip is matches the color of the stock bike’s heatshields. And the satin black muffler includes a custom heat shield to smooth the transition from the stock head pipes to the Cobra muffler. The tip uses seven, 12-point bolts that also give the dished tip a distinctive, almost aircraft quality look.
The muffler comes with a 3-inch core encased in proprietary Cobra sound tuning materials with specific acoustical dampening and thermal insulation properties. The deep bass notes are made possible because of class-leading resonance absorption and prevention.
The frequency and location of the perforation patterns in the high-flo core creates significant sound scattering in the mid frequencies, which helps to enhance the low frequency tones. The high-flo core itself is a massive 3-inches in diameter which gives the muffler an aggressive look without the objectionable sound levels.
