jasma muffs with a 2 inch diameter in piping..a friend told me that the sound produced from removing the resonator from the muffs of a low torque engine would destroy the sound....i want 2 have a "rooooaaarrr" even if m running in a low rev....jasma muffs are quiet during low revs and only produce a "rrooooaaarrr" when it reaches 5000 rpm... dats y i wana remove the reson...
