I bought a new system for my nova gsi cos the one on it seemed to be far to small and restrictive, dont even think it was a gsi one. anyway came to fit it and it wont meet the downpipe thats on the car but i think that its been swapped and a lower model one has been thrown on, checked my mates GTE and that has a different style one.

The one on the gsi has two quite thin pipes which go into one bout 3/4 of the way down the pipe.

The one on the gte is two pipes which kinda merge to one right at the end of the downpipe and its slightly longer i think - should the gsi have this one too?

The Gsi is a 91 pre-cat and the system i have to go on it is a magnex stainless?
