Intended for sidepipe applications, these mufflers can be used in other applications and feature a raw 304S stainless steel case. These mufflers offer a quieter alternative to the glasspack style mufflers that are traditionally used in these applications, plus the Cool Shell Technology helps prevent the outside of the muffler case from seeing the extreme temperatures associated with sidepipe applications.
