MONROE, Mi. – DynoMax Performance Exhaust has announced a brand-new stainless steel cat-back for 2009 Ford F-150 trucks, bringing high-performance, less restriction and a unique sound to the popular truck model. The new cat-back system is available – including the new show-stopping tips – at performance retailers nationwide.

DynoMax, an innovator in performance cat-back exhaust systems and mufflers, is manufactured and marketed by Tenneco Inc. (NYSE: TEN). DynoMax is one of North America’s leading suppliers of dyno-proven exhaust technologies for muscle cars, diesel and gas trucks and sport utility vehicles, and sport compact/European cars.

The new DynoMax system for 2009 Ford F-150 trucks (p/n 39486) delivers impressive power improvements while opening up exhaust flow, and was built specifically for “Pure Unadulterated POWER.” The system features 3-in. mandrel-bent, 409-grade stainless steel piping, providing extended protection against corrosion. The new system also includes the latest DynoMax addition: a performance, show-styled double-walled, logo-embossed 4-in. tip. Each DynoMax system includes all OE-quality hangers and accessories for a fast, easy installation.

The DynoMax F-150 system also highlights the innovative Ultra Flo™ Welded muffler, a straight-through, unrestricted design that is dyno-proven to support up to 2,000 SCFM and 2,000 horsepower. These mufflers are 100-percent welded for exceptional life and durability, and also include exclusive Continuous Roving Fiberglass (CRF) technology to absorb unwanted interior resonance and provide a rich, deep performance tone.
