Events/CompetitionsPress Release


Monroe, MI. – DynoMax Performance Exhaust, a leader in the performance exhaust market, has announced its sponsorship of the exciting Xtreme Off-Road Race Association (XORRA). Rancho®, a sister brand to DynoMax, has also extended sponsorship for its sixth consecutive year.

DynoMax, “The Official Exhaust Products of the XORRA,” and Rancho, “The Official Suspension Products of the XORRA,” products are manufactured and marketed by Tenneco Inc. (NYSE: TEN).

“We’re excited to bring DynoMax on board and to continue our Rancho program,” said Bob Willis, Sales Manager, West Coast, Performance Products, Tenneco. “XORRA gives us the perfect audience to showcase our latest technologies and gives us some extra insight into development for brand-new, cutting-edge products.

The XORRA organization hosts several series, including Xtreme Rock Racing (XRRA) and Arena Rock Racing. The XRRA series offers an intense mix of off-road racing – from short-course, wide-open jumps and banked turns to technicial lines that can be unforgiving – to make for non-stop action from the starting line to the checkered flag. The 2010 XRRA series includes nine events.

“The XORRA is proud to have two such great partners for this series,” said Jodi Weaver, XORRA president. “Rancho carries a very strong, unmatched reputation in the off-road industry and DynoMax delivers some exciting, revolutionary exhaust technologies to our audience. This is a perfect partnership for our association and its fan base. The Xtreme Off-Road Racing series would not be where it is today without this continuous support from Rancho and DynoMax.”
