Has anyone fitted the official Skoda end pipes such as these or similar. The brochure picture shows them in conjunction with a rear diffuser - do they have to be combined?

I think there are two lenghts available now, one for the standard bumper and one for the Vrs bumper. When I got mine the only had Vrs ones and they stick out a tiny bit two much on the standard bumper. Fitting involves cutting the curved piece from tho existing pipes and welding the new ones on. They look well fitted. IMHO.
