Part numbers are 17238 twin tail pipe back box, 17234 single tail pipe, centre boxes 17232 and 17233, mounting kits if you need them are 185011 for back box and 283205 X2 for the centre boxes, I think it cost me about £138 all in delivered, and it took less than a week, the nice thing about them are the centre boxes are the same kind of shape as the VX ones, if you want the tail pipe the right length you can always add a chrome or stainless tip, that’s what I did and I kept the single pipe as I didn't want to buy two tips, it looks pretty good with an oval on it.
The worst part for me was getting the bolts out of the cats, they broke so had to drill them out, no fun under a car, but with the kits I got they had nuts bolts and washers, so that was nice, I did have a bit of bother with the drivers side box as the pipe would fit very easy in the back box, a file sorted that out.
The part numbers are for a saloon
