MagnaFlow Race Parts are rugged enough to survive grueling races, like the Baja 1000, Lucas Oil Off-Road Racing Series, Dakar Rally, Monster Jam, or even X-Games. Put to the test by drivers like Vaughn Gittin Jr, Casey Currie, Dennis Anderson and Robby Gordon these parts are tough as nails and give you that performance you're looking for. MagnaFlow's specialty race mufflers feature stainless steel bodies, muffler caps and perforated cores, with our straight through, Wide Open Performance design; our mufflers give you that true MagnaFlow performance. In addition, now that racetracks are enforcing stricter decibel level restrictions, MagnaFlow is giving the consumer another option when it comes to choosing a race part to stay within those guidelines.
