The Flowmaster “Suitcase” 53545-10 is legal for every racetrack and event on the USAC/CRA schedule. The “Suitcase” is the only muffler allowed at Petaluma and Watsonville, while recommended/preferred at Chico’s Silver Dollar Speedway.

For USAC West Coast, the new muffler rule will go into effect by the March 9th event at Tulare’s Merle Stone Chevrolet Thunderbowl Raceway.
