It looks like they follow the NHRA rules so good luck. http://www.cecilcountydragway.com/pdfs/2015-General-Rules.pdf

Zoomies are allowed in OL 10.5, rules state that mufflers are required on all entries and that inserts are not mufflers. Just curious what guys are using, decker ran zoomies on both cars, Essick runs zoomies as well, they may be others. Trying to figure out if we should go with a traditional collector or the zoomies.

If the rules state mufflers required then the collector style header is going to be the simple solution. I built zoomies with a bullet style muffler in each tube once but I never got any feedback after the fact on performance or decrease in sound so I couldn't tell ya anything good or bad there.
