Removing exhaust valve's servo's/motor's info

Some one enlighten me,im running a full exhaust system and disconnected all the cables that used to be connected to the stock exhaust,so my question is can the exhaust valve servo's be removed and disconnected and will the bike show up any fault codes on dash or is there something in the hp parts list that corrects any fault codes once disconnected.???????? Cheers

I'm pretty sure it does throw a code but is considered a soft code as it does not show up on the dash but can be read by the dealer when hooked up for diagnosis. Could be wrong but I disconnected my rear servo and never showed a code on the dash but dealer said there was a code showing up in diag.

I saw a post somewhere that even with the servo motors removed the ECU showed the same fault code as the cables disconnected. You could try unplugging them as a first step, then if there's no issues go ahead and remove them. I kinda like that clack clack noise when I turn on the key, so I left mine on.

I have all my servo remove no light at all. Does through internal codes but no effect on how the bike runs.

That's right, only your dealer will know for sure.
