I’ve been messing around with my ANSA mufflers too and have had some success by drilling out the baffles. Too expensive of an item for me to cut open! I don’t have access to the main pipe that has all the holes in it but it looks like it has around 320 1/8” holes. The holes could be 3/16” or larger but I cannot tell for sure. This is what I’ve done so far http://www.panteraplace.com/page200.htm

From my calculation each 1/8” hole would have an area of .0127 sq in X 320 = 4.06 sq in total open area for the center pipe and that’s a lot larger area than the inlet pipe that has 2.4 sq in on my system. Is it possible that the restriction is caused more by the limited number of holes in the baffles and not necessarily the center pipe? I realize that a total area made up of many small holes does not equal the same flow rate as one large hole of the same area.
