These PowerFlo exhaust systems from SLP are constructed entirely from mandrel-bent 304 stainless steel. Their exclusive modular design allows for easy interchangeability between mufflers and SLP resonators. They feature high-luster Loud Mouth II mufflers that combine great looks, superior flow, and a deep, muscular tone. They're designed to OE standards for fit and durability. These systems emit a smoother, mellower tone than the Loud Mouth systems, and yet give you a subtle, aggressive edge under hard acceleration.
