What's your main reason for replacing the exhaust system? BTW I'm also in a struggle on what to do myself. It might end up being a terrible waste of money.
The main reason is to get a better tone out of 35is, but you are right it is quite good stock. I think the "golf tee" mod is the best way to go, for now. Already dropped 1700 euro on ESS/Lux Halo/smarttop. A "free" exhaust mod will be welcomed, and cant forget stubby antenna which is almost free.
