My rear bumper is a little battered on my Sdi fabia, so i managed to pick up a VRs one for

No , the exhaust trim is made to dip under the standard bumper then come back up again , it won't look right on the vRS bumper. I dont know whether a Fabia vRS back box would fit your car , but you could have a custom one made up I suppose.

From that post, it looks like there are ones for the Vrs bumpers

The parts that are mentioned on that thread are the exhaust pipe trim (which you talked about) , there may be 2 versions , one that is used with a standard bumper , and the other to be used with a standard bumper that is fitted with the Skoda acessory rear skirt (part of the body kit that was availible for the early Fabias , it isnt listed in the current accessory book) , the other part is the rear back box that was availible for the 1.4 16V engined early Fabia. None of these parts are made to suit the vRS back bumper , AFAIK only the actual vRS rear box lines up properly with the cut-out , unless you get a one off box made for your car. All info AFAIK of course , someone may prove me wrong!!

a VRS rear bumper for £25 Only???!!!

Stuart, give C & C a call over in Hillington. They might be able to sort you out with either an exhaust tip or if you find a cheap vRS back box they should be able to weld it onto your existing system.
