Opportunity to Enter Free 'Power to the Wheels' Dyno Tour Competition for Chance at $40,000 Grand-Prize Purse

 MONROE, MI, February 7, 2007 - DynoMax Performance Exhaust will launch an exciting national dyno competition - the "Power to the Wheels" Dyno Tour - that tests the horsepower and torque of muscle cars at popular automotive events in 2007, giving enthusiasts a chance to compete for a $40,000 prize purse and other event-level prizes.
    
 DynoMax, the performance exhaust brand of Tenneco Inc., is one of North America's leading suppliers of dyno-proven exhaust technologies for passenger cars, light trucks and sport utility vehicles. DynoMax products are available through thousands of leading North American exhaust dealers. DynoMax created and developed the "Power to the Wheels" Dyno Tour.
    
 "The DynoMax Power to the Wheels Dyno Tour allows our customers to prove the true power and performance of their vehicles when matched with a DynoMax exhaust," said Beth Mooney, brand manager, DynoMax. "Plus, they get the chance to compete at the '07 SEMA Show - one of the industry's most exciting and coveted shows - and win their share of the $40,000 prize purse."
    
 DynoMax will offer $100 and $50 pre-paid gift cards to first- and second-place winners, respectively, at each of the events, including the series kick-off event at Summit Racing Equipment's retail store in McDonough, Ga., and others. The daily first-place event winners will be entered into a national ranking for a chance to compete at the Winner's Shootout during the 2007 SEMA Show in Las Vegas for the

$25,000 grand prize, $10,000 second prize and $5,000 third prize.

      At the completion of the final event-level competition, DynoMax will review the first-place winners from the events and invite the top-horsepower vehicles to compete at the 2007 SEMA Show.

Event-level winners will be determined daily at the scheduled events.
     
To win, entrants must use a DynoMax exhaust system and/or muffler at the time of the dyno run. Competitors are required to make two back-to-back dyno runs and are not allowed to make any modifications between pulls. Entrants can choose the best of either pull. The winner is based on peak horsepower from the best of two runs for the complete contest. In the case of a tie, peak torque will be the deciding factor. Entrants who do not have DynoMax products are not eligible for the competition and are subject to a dyno fee ($75). Competitors can register online at www.dynomax.com prior to the event or on-site at the DynoMax Dyno Tour exhibit. The Winner's Shootout will take place during the 2007 SEMA Show, Oct. 30 to Nov.
