Has anybody fitted an after market exhaust to V4S Streetfighter without a remap? As Zard and Austin Racing don't mention needing a remap and Zard actually say you don't need one.
Which Streetfighter ? If your bike has the O2 sensors fitted in the exhaust down pipes, the ECU has been known to generally cope. My 1200 Multistrada did with a Leo Vince system but you definitely need the sensors in place. Andy
If the V4 SF is similar to the V4 Panigale, the only ECU performance upgrade is by download from Ducati for the Akrapovic. If it were me, I'd wait for the warranty to expire before looking at a change. Andy
