They're made by Coast Fabrication. They manufacture the Burn's mufflers and are identical except they tac their logo on instead. Here's a link.
The website isn't particulary instructive and you have to hunt around a bit. I actually found the Burns site to have better visuals. I think prices are the same.
I don't know about the sound level. I have a set 4.5" single stage units on my GT40 and I don't find those objectionable though they may be for some. I went with the 6 1/4" diameter single stage units 3" in & out and am expecting them to be somewhat more mellow than the ones on my 40 although they are a little shorter so we'll see. Coast also has a 2-stage unit that is identical in dimension.

Coast will make custom lengths for you at request and pretty much same $ within reason. Your choice of packing. Glass only if you want to save weight or stainless scrubble or mesh if you want more durability.
