The Muffler Rule for the USAC/CRA Sprints this weekend at Hanford's Kings Speedway will be the standard 95 db's at 100 feet.
The Manzanita / Knoxville Mufflers will NOT meet the requirements.
At present, the only tracks requiring the "quiet 180 mufflers" are Perris and Ventura. If there are any changes, we will pass the information along.
