Placing a "plug" in the center of that baffle will go a long way toward making it a functional muffler. Right now the sound just moves straight on through with little change in sound.
If you want to experiment and can live without the baffle for a couple weeks (6 days shipping each way)....mail it to me and I will weld a plug in the center for you.
You don't need to cut the baffle in half - you can insert a round plug from either end and just weld it in place through a few small holes drilled into the baffle - or you can use a grinding wheel and cut a slot halfway through the side and insert a round piece of metal and weld it in place.
You could try placing some of the glass matt around the baffle....but it really won't help much as the holes are angled in a way that allows the pressure pulses to pass right on by. The glass matt takes away some of the higher pitched tones and will make the sound a bit deeper....but not any less loud. And the glass matt burns way pretty quickly.
