New two-muffler DynoMax system

DDMax_39535-CMYKynoMax Performance Exhaust has launched a new performance exhaust system as a result of customer feedback for 2012-15 Jeep Wrangler Unlimited 3.6L models: the DynoMax QuietCrawler (Part No. 39535).

The QuietCrawler system was designed for extreme off-road driving and rockcrawling – ideal for lifted JKs – and includes two mufflers, an oval Ultra Flo welded muffler that helps to reduce sound without sacrificing performance, and a Race Bullet muffler that acts like a resonator and helps to eliminate drone. The new DynoMax Jeep system helps increase torque by 12-ft. lbs. and adds up to 11 horsepower.

The stainless steel DynoMax Ultra Flo oval muffler, one of the brand’s most popular designs, is engineered to increase exhaust flow and provide a unique, sporty sound while fitting into a smaller, tighter space.

Inside the new system is a DynoMax Race Bullet muffler, an addition to the tailpipe routing within the system, which responds as a resonator in this application. The system also includes 2.5-inch mandrel bent piping for increased flow and is constructed from stainless steel to protect against corrosion.

Like all DynoMax exhaust kits, the JK system includes other necessary hardware and instructions for an easy, bolt-on installation.

DynoMax Performance Exhaust offers a full complement of exhaust products for Jeep vehicles, including torque and horsepower-enhancing DynoMax VT, Super Turbo and Ultra Flo exhaust systems covering applications 1986 and newer.

A DynoMax Limited Lifetime Warranty and an exclusive 90-Day Performance & Sound Guarantee cover the latest DynoMax Jeep exhaust system.
