1.8 backbox on gti 6

[C.A.R.]

Ive fitted a gti6 backbox to my 1.8. The difference in the exhausts is the manifold and the cat. Rest back from that should be interchangeable.

Only the backbox is interchangeable, mid-pipe is different as it starts slightly further back I believe.

It was my understanding that it worked like this...

1800 |-Manifold-|----Cat----|-----Centre-----|-Back-|
GTI6 |---Manifold---|--Cat--|-----Centre-----|-Back-|

I think the join is in roughly the same place but the two don't mate up iirc. Certainly they are under different part numbers and the middle silencer is smaller on the GTi6, perhaps the pipe diameter is bigger too? Certainly looks like the 1.8 flares out slightly before the backbox join...
