I extensively modified my GTS mufflers with perforated Y-pipes inside the 
cans, and used race muffler packing that I got from Howe Racing.   It's 
stainless steel wool, which works just like fiberglass but lasts about five times 
longer (and costs accordingly).

Acoustically, my muffler modifications are a great success.   I have 
essentially straight-through mufflers now, but they are substantially quieter than 
straight pipes or Hall/Mind Train-style muffers.
