      Construction. This tough, heavy duty exhaust system is part of MBRP's rough and ready Black Series, able to stand up to high temperatures and abrasive exhaust clamps. The sturdy Mandrel bent, 16 gauge steel is fashioned into 2.5 inch pipes that permit strong, efficient exhaust flow, boosting torque while improving fuel efficiency by 1 to 2 MPG. The stainless steel tip is removable, so you can leave it in place while you're cruising around town or you can remove it for wheeling.

      This finely crafted cat-back exhaust system provides enhanced performance and improved sound. The chambered muffler rumbles deeply while idling and roars fiercely at high speeds. This system is designed to boost horsepower while withstanding moderate doses of trail punishment.

      Application. MBRP backs this system with a three year warranty. This system fits 2007 - 2011 JK Wranglers, but only the 4-door models.
