Developed in collaboration with Waldoch Craft this system offers a highly custom 304 Stainless Steel Teardrop exit through the bedside in front of the tire. This system uses an Outlaw series muffler for an aggressive sound level and increased performance. 3.00-inch mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and durability. Max dyno gains of 21 hp and 25 lb-ft at the rear wheels. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation.
