As per my MOT thread, I've been looking at potential new back boxes for my 120. I have seen a Stainless steel Piper 3.5" rolled in tip for £195. Would I be paying way too much? as the mild steel one is only £145.
Prospeed in Cardiff. Give Charlie a ring, mention my car and the forum and see what he can do for you. Not too far from you. Albeit mine was done a few years ago but I shouldn't think it would be much more.
£300 aint too shabby in all fairness. But I'd have to take into consideration the cost of driving to Cardiff and then paying the toll for the bridge. I wont be getting the exhaust just yet as I will have to save some pennies up first!
