You are doing the oranges/apples again.  S cars have a different exhaust.  Much better stock than the Ur-q.
I believe this is the reason 20v Ur-q went to dual CATs with dual pipes all the way to the centre muffler.

I don't want this to get into aregument "why?".  
All I want is a 3" system that is bolt on and others (who choose to) can purachase as well.
