Hard to tell from the photo but my TC silencer doesn't look like that so I'd guess it's either S2 or maybe even S1 ?
My TC has bends on the inlet and outlet pipes. The inlet has (very) roughly a 45deg bend downward to meet the pipe coming from under the gearbox and the one towards the rear has 2x45deg (guesstimate) bends to clear the body. I'm pretty sure the one shown wouldn't fit on my car.
As to whether that will fit your S2, from my experience with any aftermarket exhaust you have to be prepared to do at least a small amount of "adjustment" to get them to fit. The bore and pipe lengths will be right but I don't expect the bends to be accurate !
