Mk1 gti cabrio exhaust modded to mk1 driver???

Will it fit and if so what modifications needed (apart from reducer pipe from manifold to middle section)

so what exactly do you plan to fit? the whole GTi system from the down pipe back? or the manifold and down pipe aswell?

I think it might depend on what year cab the exhaust is off but I'm not 100%

The whole system fron the downpipe back. The cabrio was a 1984 shell as is the driver shell.
