Muffler resonating frequency

Hi,

I am new to this forum :)

I am trying to design a muffler and so am in the process of determining how much fiber glass I need behind the perforated pipe. I was wondering if anyone knows how to workout the resonance frequency for a muffler? I have a 599cc engine with 11000 rpm and 70bhp. I know if I put 6 inches of fiber glass then it will absorb around 99% of the sound frequencies but I wanna reduce the amount of space needed for the fiber glass to say 3 inches. So it only absorbs to the required frequencies.

If I can get a resonance frequency then I can workout the diameter of the perforations required for the space available.
