I am building a super gas car and I would like to buy a muffler insert to put into my header collector. I want the muffler insert that will pass the NHRA sound requirements guaranteed no questions. Anybody got any recommendations?

The Dynatech Vortex cones will pass tech with no problems?

NHRA has looked to see if you have somekind of muffling but have never seen or heard of them checking for sound with a meeter !!!!!!

Hammertime,

I checked with Ben Wilson Div 7 tech director and he would not recommend any brand or type. He suggested I talk with some of the other supergas guys to find out what they are using that passes tech.
