resonance frequency

[Joerg]

Hi to all of you,

is there anybody out there who can help me with the equasion to calculate the lengh of an exhaust pipe accordingly to the resonance frequency of the exhaust gas. I would like to build in a silencer but I don't want to sacrifice performance, so the exhaust puff puff should be in resonance with the total lengh of the exhaust.

I deeply appreciate your help.
