so im a xb noob and have a couple questions. just got my 2003 xb9r. it already had a k&n filter and wanted to go with a jardine exhaust but ive heard that i will actually lose power. ive read that the ecu can be remapped, by who? or would it make sense just to get a race ecu? i bought the bike assuming i could go out and buy a power commander which seems not to be the case. help me out guys.
