DynoMax Releases Evolution Competition System for 2007-11 Jeep Wranglers

DynoMax Performance Exhaust products now has a new off-road “Evolution Competition” system for 2007-11 Jeep Wrangler 3.8L V6 models (Part no. 39516).

Ideal for rock crawling and lifted JKs, the new DynoMax “Evolution Competition” system is designed to dump the exhaust in front of the rear axle, providing the space and flexibility necessary for an off-road suspension system and extreme off-road use. This exhaust kit was designed in collaboration with Off-Road Evolution, Fullerton, Calif.

The new system includes a stainless steel DynoMax Ultra Flo polished round muffler, engineered to maximize exhaust flow and provide an aggressive, unique tone. The Ultra Flo muffler is dyno-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 2007-11 Jeep Wrangler also includes a 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. The kit also features other necessary hardware and instructions for an easy, bolt-on installation.

Each and every DynoMax product is built to the brand’s theme, “Pure Unadulterated Power,” and is backed by a limited lifetime warranty and 90-day Performance and Sound Guarantee.

Available exclusively from DynoMax, the 90-day Performance and Sound Guarantee lets enthusiasts try the system for 90 days. Consumers can return the product within 90 days for a full refund of its purchase price. The system also is covered by a limited lifetime warranty. Additional details and restrictions apply and can be found at

A leader in performance exhaust products for the Jeep market, DynoMax Performance Exhaust products are manufactured and marketed by Tenneco Inc.

DynoMax is one of North America’s leading brands of dyno-proven exhaust technologies for late-model and classic muscle cars, diesel and gas trucks and SUVs.
