Would this fit & replace the vrs's rear silencer?

you could do what i done and get the front silincer removed

You could look for a local Powerflow outfit. The mrs had a cat back system on her 1.2 12v - sounds excellent. They will fit boxes to make it as loud or fruity as you want. £240 all in.

Anyone know if this will fit http://item.mobileweb.ebay.co.uk/viewitem?itemId=320743747730

You can use this but you'll need to take it along to an exhaust place and ask them to fit it, is it will probably need the flanges fitting so I can be a swap, or chop the old out and weld this in but there might be a bend required, hopefully someone will have a better answer for you.
