Hi Brummie, I hope that this means you are from B'ham - so am I. I have been looking around for a set of good loud pipes and the cheapest are from Custom Cruiser @ Derby. They do 2 sets: short turn outs (no baffles and serious rejetting) and long megaphones - similar length to the TBA (some baffles but much louder). I have asked Mike who runs CC to take a set to the Rock & Blues Custom festival (w/e of 28th July @ Derby) so I can see how they fit onto the TBA. I still think that the originals look the best and I might try to knock out some baffles. On another note I have just bought the AI removal kit in the UK for about £23
