right after sparking up alot of interest on this and wanting to do this my self ive finaly got my arse into gear and put up a manual on this haha
p.s im not saying this is the perfect way to do it but it works perfectly on my car and should do on every body elses.
i have done this so that the decat is completly removable so there is a bit of extra work involved but its worth it
tools and things:
general socket set.
welder
grinder
half moon clamps
some spare straight pipe that is the same size or very slightly bigger than the standard pipe in the middle.
right first things first you need one of these pipes!!!
( im not selling the pipe its just an ebay link!)

right once i bought this pipe basically i took the cat out (make sure lots of rust off is applyed on manifold bolts) for the other end if you have the centre box in (take it out its much better ) just undo the clamp and then slide the pipe out.
once you have the cat off cut the mount that links onto the manifold pipe off as close as you can to the actual flat plate. this makes it easer to measure and weld on.
once you have that plate off put the cat ontop of the decat pipe and see where the cut on the cat lines up on the decat pipe. (always cut so theres more than you need incase of a mistake !!!).
This should give you the length you need so that if you bolt the plate that you cut off the cat back onto the manifold by its self then you can hold the decat pipe in where its gong to go just to see its not to long at the front to make sure it doesent hit bottom when driving.
right if you have the centre section in ignor this next paragraph and move onto the next one.
for those of you that already have removed your centre section this is easy as
