I'm debating whether to do this. Akra has a full exhaust system for $1300, and 2wheeldyno has a flash for $300. I don't have the tools nor expertise to replace the exhaust system, so I would require a mechanic for labor, so I estimate the total cost to be roughly $2k, conservatively. Has anyone done this? Ivan does not offer the flash for this model year, unfortunately. I'm also not sure about 2wheeldyno, as I haven't seen any posts regarding this type of remap. Its rather expensive, but it would be cheaper than trading in the bike for a ZX10 and modding it for better ergonomics...not to mention a ZX10 would be a terrible street bike, which is where I do my riding.
