Monroe, MI., Fri., Jan. 14, 2011 – Posting an additional 16 horsepower and 13-ft. lbs. of torque at the dyno, the new DynoMax 2008-10 Ford F-250/F-350 Super Duty system gives owners a boost of horsepower and torque while freeing up exhaust backpressure.

The system is now available at thousands of performance retailers throughout North America. The new DynoMax system (p/n 39469) – built to match OE routing and provide added performance and sound enhancements – fits 2008-2010 Ford F-250/F-350 Super Duty 2WD/4WD 5.4L/6.8L V8 trucks. The system does not fit 2008-10 Ford F-350 Chassis Cab trucks.

The new system includes 3-in. stainless steel mandrel-bent piping to protect against corrosion. It also includes one of the brand’s popular DynoMax Ultra Flo™ Welded mufflers, a high-flow stainless steel muffler design built to maximize exhaust flow and provide an aggressive tone.

The Ultra Flo Welded muffler is 100-percent welded for added durability and longer life. The muffler also includes Continuous Roving Fiberglass (CRF) technology to absorb unwanted resonance inside the cab while providing a rich, deep performance tone.

The single, cat-back system also includes necessary OE-grade band clamps, u-bolt clamps and 4-in. stainless steel slant cut, logo-embossed tip. All of the necessary instructions are included for fast and easy installation.

The new stainless steel system is covered by a limited lifetime warranty and exclusive 90-day Performance and Sound Guarantee, an offer that lets enthusiasts try the system for 90 days. Consumers can return the product within 90 days for a full refund of its purchase price. Additional restrictions apply and can be found at www.DynoMax.com.
