The Cobra 4" Slip-Ons provide an increase in horsepower and torque with a deeper, more aggressive exhaust note. The 4" muffler body has proprietary technology to help prevent bluing, as well. By locating the louvers further back in the mufflers, super-heated gasses have a chance to cool before exiting the silencer core, which makes the Cobra Dresser mufflers virtually blue proof.
Note: Headpipes sold separately.
