Just sorted everything with the tiptop performance. Full turbo back exhaust i.e. 3" d/pipe, sports cat, centre pipe, axle pipe and back box for £387. They going to use T304 stainless steel to build one and I got choice to select tip from 12 available.

Also lifetime warranty for it (as long as I own the car). Shame the day they can book me I can't make it. Need to sort this as soon as possible.
