Fitted a non-res catback to my '07
Ibiza FR, and it's a lovely exhaust. Noise is great, fits quite well. Mine is knocking against something underneath though, still haven't figured out if it's the rear bridge between the wheels or whatever, but should be easy to fix once i get a proper lift to drive the car on.
A note to keep in mind btw: If you've got the facelifted FR or Cupra (the bigass bumper), be sure to mention it to Milltek / reseller, or you might end up with a backbox that's too short!
Also, it's not on their site, but they make a very nice oval backbox for the FR that looks almost exactly like the OEM Cupra:
