On my 99 EC200 I just bought a new FMF TCII S/A, that can is super heavy and bulky, but it is what it is... not many choices out there for the older bikes. I still have my OEM, but it is loud and no spark arrestor.
I have my old TCII I may cut it up, make it shorter like a FMF Shorty with the Turbine Core, not sure how it would perform or what db it would blow.
DEPUSA has some nice stuff, but not sure if the are S/A?

For what it is worth I have a Leo Vince on my YZ 125, with spark arrestor screen, pretty much a required item to ride on public land here in CA.
Several weeks back the Funky Chicken National hare scramble the YZ blew a 86db at the sound check....that thing is super hush! Love it, the only real pain in the butt is removing the screen and cleaning it.
So far very happy with the Leo Vince product.
