Built with 2.50-inch 409 stainless steel mandrel-bent tubing and Gibson's SuperFlow chambered muffler, part number 619687 exits straight out the back with a 3-inch polished T304 stainless slash-cut tip. No welding required this is a complete bolt-on system with all factory-style hangers and hardware included.

The dual-inlet muffler (6-inch round body, 24-inch length, 2.50-inch offset inlet and outlet) delivers an aggressive exhaust tone while keeping interior drone lower than virtually any other performance exhaust on the market. Dyno testing shows 10–15 horsepower and 15–20 lb-ft of torque gains, with the power band concentrated in the 1,800–3,000 RPM range where the Explorer and Mountaineer spend most of their time under load towing, climbing, merging, passing.\u003c\/p\u003e\n\u003ch4\u003e409 Stainless Mandrel-Bent Tubing\u003c\/h4\u003e\n\u003cp\u003eGibson 619687 uses 409 stainless steel throughout the pipe system with mandrel bending to maintain consistent 2.50-inch diameter through every bend no crimping, no restriction. The single tip is a 3-inch polished T304 stainless slash-cut unit (clamp-on, 8 inches long) that exits behind the rear tire at the stock location. The slip-on flange connection keeps installation simple.
