We bought some chrome sidepipes (2" in, 3" out) from an american company called Patriot. They look the biz, but not SVA friendly, but could easily be modified.

They import the pipes from the states, so you don't have to worry about import duty/shipping etc.
They either cost £189 or £199 delivered (inc VAT). This price was only a tad dearer than getting them from the states yourself.
