LAS VEGAS, Nov. 3, 2009 – Highly modern graphics and photography, strong technology stories and interactive capabilities lead a long list of new website upgrades by DynoMax Performance Exhaust, a leader in the performance exhaust category.

The new DynoMax website – built for “Pure Unadulterated POWER” – is located at www.DynoMax.com. DynoMax is the performance exhaust brand of Tenneco Inc. (NYSE: TEN).

“DynoMax will distinguish itself from other brands through several industryleading innovations this year, and we’re excited to showcase these on the newly designed and re-engineered website,” said Joe Pase, director, performance products, Tenneco. “In fact, we’re redefining the ‘perfect’ exhaust. It’s going to be an incredible year for DynoMax and for enthusiasts looking to upgrade or replace their current performance exhaust systems or mufflers.”

The new website, which features new graphics and interactivity, highlights new products like the stainless steel cat-backs for the 2010 Chevrolet Camaro, 2010 Ford Mustang, and 2009-2010 Ford F-150 and several other models. DynoMax provides new, highly detailed product pages plus sound clips of systems and mufflers that make it even easier for enthusiasts to experience the DynoMax Difference.

“DynoMax has made it easy to see our technology story for each product, every application,” Pase said. “Looking for a Tundra exhaust? Click on that application, and you immediately know it increases horsepower by 37, torque by 44-foot pounds, and includes an Ultra Flo Welded muffler. That’s what our enthusiasts are looking for: instant access to our technology advantages.”

The website also includes a highly dramatic crate engine demo, where the user can identify preferred mufflers, hearing actual sounds, giving enthusiasts exciting insight into the exclusive flow and sound advantages of DynoMax products.

Users also can link to the DynoMax Facebook and YouTube pages, making it easy for enthusiasts to connect with the brand and interact with their own cars and exhaust experiences.
