Performance ECU
 

I await a Ducati Performance ECU part # 96518607B for open race silencers. Will I be able to remove the O2 sensor and exhaust valve on my 1098 and fit a K&N air filter?

96518607B is for racing silencers (slip ons), and not the full system.

I'm not sure if it removes the exhaust valve or not (I don't think so) but it definitely won't remove the o2 sensors as they are in the downpipes.

For the full system that removes both o2 and exvh you will need 96518507B 1098S Full System.
