i dont know what brand mine is, but is the 100cell.
did have a single cell cat like cam.. but the $5000 minimum fine EPA gives you is really not worth a single cell cat. althought 100cpsi cats arent EPA approved, you still wont cop the stupidly large fine, as they see it as "atleast you have something in there" they'll just slap a yellow sticker on there and say go get a proper one.
