▲ 1 r/YamahaR9
Hey,
I am picking up R9 and wanted to consult about exhausts.
Thinking of immediatelly ordering SC Project one (SC1-R probably), but I am not sure about programing ECU, cause it would void warranty immediatelly. I am based in EU, hence no issues with second gear having a dead spot.
Is it mandatory to remap ECU, will it throw some engine error if exhaust with no cat is used?
I am also interested to hear what exhaust you suggest!
Thanks!
