Hi guys, can anyone help my HP 4 comes in April & I want to do a few alterations, on the Exhaust. I want to fit the Austin racing GP2R de cat, which should fit straight on, do I have to have it re mapped & a new ECU fitted, if so who can do this for me. I'm buying the bike from Benham BMW Wolverhampton, & they say it will invalidate the warranty, can any one help me on this please. Also fitting a tail tidy!! What would you recommend, & do I have to splice the cables to the indicator & tail light.
