I bought a one for my 8v was supposed to fit 8v/16v and Vr6, needed a quite bit of fitting before it would fit properly but it is a cheap sh!te copy.
I have a sport cat which I bought for £50, when I get five mins I am going to cut the flange and tubes of the old one and weld it together, hopefully I will be able to get the exhaust sitting right by doing this
