It appears as though the 2010 RRS HSE exhaust it the same as the 2006-09 SC exhaust - straight tip and all except on SC the resonator is Polished Stainless and has a double wall tip. All the pipes up to right before the resonator are 55mm and just like the SC there is a conversion to 60mm right before the bend to the resonator.
I have not examined the new 2010 SC exhaust yet but I imagine that has to be larger to deal with whopping thrust of 515 horses whining out of that supercharger.
