>>>That is exactly what I did.   Lots of work to cut the muffler can open, 
gut the internals and replace with a Y-pipe of perforated tubing (I actually 
used solid tubing because I couldn't lay hands on perforated tubing in 
time, and used a plasma cutter to cut holes in it), and filled the can with 
stainless steel muffler packing to provide sound absorbtion.   The result was 
only a 12 hp gain; Dan Jones did the before-and-after testing on the dyno, and 
then did the math and discovered that the area of the pipe entering the 
front of the muffler was substantially greater than the area of the two 
resonator tips, hence the start of this thread--the suggestion that removing the 
resonators from the tips would free them up.
