LAS VEGAS, Tues., Nov. 1, 2011 – Available in early 2012, DynoMax^® Performance Exhaust will release a new performance cat-back exhaust system that delivers a throaty exhaust tone and drone-free performance to the popular 2011-12 Ford F-150 3.7L 6 cyl. and 5.0L/6.2L 8 cyl. trucks.

The new stainless steel system (p/n 38514) features a buffed and polished 3-in., single-walled 12-in. long slant-cut tip and 3-in. mandrel bent piping, wrapped around the exclusive DynoMax VT™ muffler. The exhaust systems fit extended cab short bed and crew cab short bed Ford F-150 models.

“The DynoMax VT performance exhaust system was designed to improve performance, get noticed and deliver drone-free acoustics,” said Joe Pase, director, performance products, Tenneco. “Now you can be satisfied when you’re revving your brand-new F-150 and when you’re just cruising.”

The DynoMax VT muffler controls interior drone common among performance exhaust systems while allowing an open, throaty sound during acceleration. Designed around the precisely calibrated patented internal valve, the muffler’s routing redirects the exhaust flow during cruising conditions to limit unwanted drone.

The VT muffler also includes stainless steel construction; slotted bushing ends; exclusive Continuous Roving Fiberglass (CRF) technology that absorbs additional unwanted interior resonance and allows for a rich, deep performance tone; and a show-stopping DynoMax VT logo-embossed body with a high-impact micro-finish.

The 100-percent welded muffler included in the F-150 system was engineered specifically to deliver DynoMax’s “Drone-Free Performance™” and feature a straight-through, unrestricted design that is dyno-proven to support up to 2,000 CFM and 2,000 horsepower.

All necessary hangers, clamps and other hardware also are included in the kit. DynoMax systems include handy, full-color installation guides for fast and easy installations.

DynoMax is manufactured and marketed by Tenneco (NYSE: TEN) and 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.

The new system is covered by an exclusive 90-day Performance and Sound Guarantee 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. The system also is covered by a limited lifetime warranty.
