What I'm after is just the back box. I have just swapped the nasty black plastic valance on swmbo's GT for a Gti type with the opening for the twin tailpipes, at the moment it looks a bit sad as the GT140 has the concealed exhaust pipes, my mecahnic is going to bodge a couple of chrome tail trims for the interim, but eventually I want a complete rear silencer. While trawling through eBay I have found a complete system from a mk6 1.4 Tsi, which on the mk5 is the same as the GT170 and Gti.........
This is the one I have my eye on -
Edit: Just had a look under my car, and the routing is different but the back box looks the same.
