Where to buy standard exhaust centre section?

[Raw]

I need to buy standard exhause centre section but all the usual culprets (GSF, Euro car parts etc.) can't get them. I've tried loads of aftermarket exhaust places but nobody in the UK can get them.

I've not tried VW but most G40 specific stuff is obsolete now or helishly expensive - they are my next port of call though.

Does anybody know where to get them from?

The GT mid box is approx 1mm smaller diameter at the mid-box->back back joint iirc. I used one of these pattern part GT mid boxes (buypartsby) to an eBay pattern part G40 back box  - no problems
