that's called a twin-loop or twin-pass style muffler and it's the medium between the high flow/more noise "straight-through" design and the low flow/less noise "chambered" design. its got a little bit of both. the air flow travels twice through the muffler as you can tell from the design. the S2000 comes stock with two of this style muffler. Mugen makes a system using this style muffler called the "Mugen Twin Loop Silencer". i hear it sounds awesome, but it costs about $800-$1000.

i would contact the guy and see if the inside is stainless steel or glasspack. if its the cheap glasspack, which it probably is with that price, it will deteriorate quickly and sound like *** sooner than later. DC makes one too, but i dont know what the insides are made out of. hope this helps.
