OMG.
Thought I'd remove the pre cat and after reading threads on here it seemed pretty straight forward.
Try to get the exhaust out the mid section joint was a nightmare - especially with the car up on little ramps.
Took me 3 hours and several cuts, bruises and aches though it starts
Haven't been out as I'm battered now though after revving it the first time it did have a little pop
Revved it a bit more and all seemed good.
Might go for a run later and see what's what.
Again, great help from the forum and a valuable resource for GTi owners....
