Monroe, Mich., Sept. 17, 2012 – After the release of the industry’s first off-road “Evolution Competition” system for Jeep® vehicles this past spring, Tenneco’s DynoMax® performance exhaust brand has added additional coverage of the popular design to fit 2012 Jeep Wrangler Unlimited 3.6L V6 platforms (Part no. 39522).

Available at performance retailers nationwide, the DynoMax “Evolution Competition” system was designed for extreme off-road driving and rock crawling and is ideal on lifted JKs. Engineered to dump the exhaust in front of the rear axle, the DynoMax kit provides additional space and flexibility to run an off-road suspension system. This kit is for off-road use only. The original Evolution Competition kit was designed in collaboration with Off-Road Evolution, Fullerton, Calif.

Each of the Evolution Competition systems were engineered for the 2012 Jeep Wrangler Unlimited 3.6L V6 vehicle utilizes a stainless steel DynoMax Ultra Flo™ polished round muffler. This muffler – one of the DynoMax brand’s most popular designs – is engineered to maximize exhaust flow and provide a unique, sporty sound while fitting conveniently into a smaller, tighter space. The Ultra Flo muffler design is DynoMax-proven to support up to 2,000 CFM and 2,000 horsepower through a straight design that ensures unrestricted exhaust flow and reduces backpressure.

The system for the 2012 Jeep Wrangler 3.6L V6 vehicle includes 2.5-in. all 409-grade stainless steel, mandrel bent pipe for extended protection against corrosion, and two stainless steel 2.5-in. band clamps. Like all DynoMax exhaust kits, the JK system includes other necessary hardware and instructions for an easy, bolt-on installation. Tenneco also released a similar DynoMax kit for 2007-11 Jeep Wrangler 3.8L V6 models (Part no. 39516) that is available at performance retailers nationwide.
