Take yourself off to Powerfiat, Rog will get you one made up in stainless steel, for +/- the same as an OEM exhaust. (It involves going to a local place that Rog has a dela with)Make sure you go for the two silencer option.
I had a supersprint prior to this, I don't recommend it.
Just in case anyone else is interested, Blueflame also do a system that's meant to be very good quality, and there are, IIRC, options available from Peco and Ragazzon, as well as the usual custom stuff from Powerflow and the like.
