“The top five drivers faced some intense racing at the MetalCloak Stampede, finishing within seconds of each other rather than within minutes like the other races in the series,” said Chris Gauss, director of performance products. “It was great to see our drivers nearly sweep the podium. It’s going to be an exciting 2015 ULTRA4 season!”
In true ULTRA4 racing action, Shirley blew his engine during the open practice session and was able to do a complete motor swap with the help of Tilden Motorsports/Pacific Fab. Shirley started the race in the 11th spot, and worked his way to fourth before getting bounced to fifth as his rig started acting up again.
As “The Official Performance Exhaust of ULTRA4 Racing,” DynoMax performance exhaust has powered the past six King of the Hammers champions across the finish line. The ULTRA4 MetalCloak Stampede features rock obstacles, hairpin turns, high-speed passes and a two-mile course that’s completely visible to attendees. More than 90 teams competed in this past weekend’s events.
Most of the participating teams are running the brand’s popular Race Bullet muffler. The Race Bullet muffler features a compact, round, straight-through design for maximum exhaust flow and power. The Race Bullet muffler features an aluminized or stainless steel design for longer life, and can flow in any direction. It is ideal for tight clearance installations, is available in as small as 9-in. overall length and is lightweight.
