Has anybody got this exhaust(LASER "X-treme" Exhaust System Tapered (4 x) on there bike and if so, do they have any pictures/comments on performance/sound etc. I am seriously thinking about getting it but would like to hear some feedback before I do. Can get it here in the UK for about £485 and was wondering whether anybody has seen it cheaper? Any comments appreciated? the tappered pipes look really good!!!
