Mufflers reminder for Super-class racers

With an influx of new drivers to the three Super categories (Super Comp, Super Gas, and Super Street), a growing number of cars are appearing at national and divisional events without any sound-suppression device.
The 2002 NHRA Rulebook reads, "When competing at national and divisional events, vehicle may not exceed 95 decibels as measured on the 'A' scale from a distance of 50 feet, at a right angle to the vehicle, with the vehicle at a no-load rpm of 3,500. Sound-suppression device not mandatory if vehicle passes testing."
Part of NHRA's mission is to preserve the right to race. In many communities, the right to race is contingent upon reducing noise and complying with local noise and muffler laws, ordinances, regulations, or agreements. Therefore, all competitors must comply with any muffler rules applicable to his or her class in the Rulebook.
The NHRA Tech department continues to do random testing of competitors for compliance to this rule, and will broaden this check in coming events.
