I went to my local exhaust shop and ordered a new cat back system for my 2.0 Sri. It's costing me £320 and I asked for the 4 inch round slash cut style. He even asked my how loud I wanted it to sound, I said not too loud as I don't want to wake the street up . I did want a 6 inch by 4 inch oval but he does not do them, they only do the up swept ones in that size. I just hope the Pro Drive kit on the rear bumper can fity once I get that also :roll: .
