My dealer told me that a team member who used to work at Akropovic left the business and started his own, this is the guy apparently. They are very good. The reason I say so is KTM in South Africa will not let you fit any other exhaust pipe on your KTM except Akropovic or else you will void your warranty. I asked about Leo-Vince and they said no, Devil ... no, 2bro's...no, but then they said that if I fit a set of wings then they will uphold the warranty. So it must be pretty good?
Only thing is a set of Akro slip ons for my 690sm cost R12000, and a set of Wings slip-ons cost R10000 so its not too much of a saving. Just out of interest and to put it in perspective, a full Leo-vince system with carbon shorty cans cost only R10000. I know what I would choose and possibly just bolt on the original cans round service time :arsenal
