GTMotoring - Akrapovic Downpipes 1M/135
For the ultimate in weight reduction, tuning potential, and racing sound, Akrapovic offer stainless steel, catless downpipes. When used in conjunction with the Evolution System, this is virtually the same setup used on the 1M Moto GP Safety Car. The high-flow downpipes do require ECU reprogramming to eliminate the check engine light and for peak power output. They are only for the dedicated track day car or hardcore enthusiasts.
ECU tune or flash is required to use all downpipes. As they remove primary catalyst.

They do make a wonderful product and their build quality does set the bar when it comes to materials, fit and finish, and welds. There are reall only two things that I had questions and they probably should be asked directly to them, but 1: Why use flex tubes in each downpipe when no one else does? long term benefit to prevent cracked exhaust and to offer flexibility in exhaust system? and 2: why not go with a flush, end to end/butt weld for a smoth transition? two section are puffed up/ flared up like any ol' blue bullet exhaust shop bender will do to make a slip fit and then weld it. Its just a cheaper way of fiting two pieces of exhaust pipes together before welding them. For the price these downpipes are, I would expect a better job on that. Either way, I know these are top quality, just wondered about those two things that no other company does. I have been very interested in the complete exhaust pacakge FWIW. Thanks.
