Available in January; Feature the Company’s Brand-New Tips

LAS VEGAS, Nov. 3, 2009 – The brand-new DynoMax® Performance Exhaust systems for the 2010 Chevy Camaro gives everything the Camaro owner wants: power, sound and looks. The new performance systems – including the new show-stopping tips – will be available this January at 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.

DynoMax will launch two systems to cover the 2010 Chevrolet Camaro 3.6L V6 (p/n 39493) and the 2010 Chevrolet Camaro 6.2L V8 (p/n 39494) models. Both systems include high-quality, 409-grade stainless steel 2-½-in. mandrel-bent pipes, a premium material that provides extended protection against corrosion, and include the new logoembossed DynoMax double-walled 4-in. show tips. All of the necessary OE-quality hangers and brackets are included for easy, fast installation.

Built specifically for “Pure Unadulterated POWER,” the systems feature the brand’s legendary 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.

The new stainless system is covered by a limited lifetime warranty and exclusive 90-day Performance and Sound Guarantee, a free-ride offer that lets enthusiasts try the exhaust system for 90 days. Consumers can return the exhaust within 90 days for a full refund of the product’s purchase price.

DynoMax also offers extended coverage of other Camaro models, including various models from 1969 and newer.
