SLP offers three series of axle-back exhaust systems, the PowerFlo, Loud Mouth & Loud Mouth II. Both PowerFlo & Loud Mouth II kits feature mufflers with a straight-through design and a ceramic-wrapped perforated core to significantly outflow traditional chambered and turbo-type mufflers. PowerFlo mufflers are slightly larger and offer a quieter exhaust note. The Loud Mouth systems replace the factory mufflers with straight through tubing for an aggressive exhaust note.
