This kit fits 2011-2014 V6 Mustangs and features an all-new ROUSH open-chambered muffler with round tips. In contrast to the conventional fiberglass-packed muffler design, this open muffler has a less inhibited sound, increased longevity (because there is no fiberglass packing that tends to break-down over time), and increased air flow for maximized power. Another great feature of this system is the elimination of the in-cockpit boom, which is common in performance exhaust systems at cruising speeds. The round tips of this Mustang dual exhaust kit are made from high-quality 304 stainless steel. The shiny finish of these tips are made with a special chrome flashing process that is dramatically more resistant to cracking and flaking than conventional chrome surfacing. The mufflers and inlet pipe are made from 409 stainless steel for improved durability. This V6 Mustang Exhaust kit installs quick and easy. It uses the factory hanger mounting points -- you don't have to fabricate your own. This kit also features spherical OE-quality clamps for a perfect fit.
