Default NHRA Super Gas Muffler requirements

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?

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.
