After further investigation it would appear the around 2010 they changed the rears to the Bosch type that I've now got, the pipe enters the top of the caliper directly and not through a section of rigid pipe on the underside like the mk5 and early mk6. I'm guessing because they're relatively new that's why I'm struggling to find aftermarket pipes. Unfortunately the local dealer won't help unless I've got the chassis or reg number of the car they came off, does anyone have access to etka to get the part no or should I just take a gamble and go with a reg no of any 2010 onwards mk6 gti and hope for the best? Really need this sorted now as the car has been off the road for a week.
