DamienC Posted February 25, 2015 Report Share Posted February 25, 2015 Hi there, I have a technical question. I am intending on removing the cat on my s1000rr to put a full exhaust line (bike will be track only), simply changing the mid-pipe. Guys at BMW tell me that I should get the HP Race ECU...which is not exactly cheap ! Now the question is...Does removing the cat for a race mid-pipe actually REQUIRES a switch in ECU ? Or can I change the mid-pipe and then wait to have some more $$$ to change the ECU ? Is running the bike with a cat-free line with the OEM ECU damageable to the bike ? Sorry for the naive question...still learning !!! Quote Link to comment Share on other sites More sharing options...
