really all im looking is the bit of pipe coming out from the back box to the center pipe, with the flange. see highlighted part in pic !!
I got a remux back box but it only has a bit of pipe on it, and i dont want to go chopping up my own incase i muck it up. :oops:

its for an astra coupe, but i think a hatchback one would do too.
Got it sorted,
