This slip-on muffler removes the heavy steel muffler and catalytic converter, just like our STEALTH Bimodal slip-on. However, it does not have the bimodal option. This allows us to offer an exhaust at a more competitive price while providing the same peak sound and performance increase as the STEALTH Slip-On. In addition to a significant weight reduction, this exhaust produces a deep triple sound without the annoying and dirty sound that many aftermarket exhausts create.
