I have bought genuine back boxes ( a la cjeeper on here) from (Beedub) on here and am getting them fitted probably at the A44 exhaust shop in Worcester... they seem very attentive and dedicated to doing a proper job.
Great, thanks! I just did the deal with the very nice chap on ebay... £120 delivered which is a bit more like it i think.
I think i will do it 2 tone, with a flat back bottom section... I've seen a few people who have done this, and it looks great!
