Speaking of another 'Ashley', you can always get a kit and weld it yourself.

For example, all the components needed for a 4:2:1 including manifold, downpipes, 4 to 2 collector, pipes and 2 to 1 collector into the silencer pipe will cost £95 for a Zetec. You can then arrange and weld at your leisure.
I have one and it's fine.
