I was more curious as to any specific differences. I understand the flow ideas and the fact of using the fiberglass to pack (which will burn especially in this configuration). Again in the thoretical sense the flow apears to be more in a strait line. You have answered my question as the ANSA mufflers had parallel flow pipes (and the involved calculations of actual flow in cfm thru the perforations) I was then wondering if your design would have an influence on the sound (dB)
