Kawasaki ZX4RR OIL FILTER CHANGE WITH YOSHIMURA HEPTA FORCE FULL EXHAUST

I made a video showing that the oil filter can be removed/reinstalled without removing the header as stated on the Yosimura Japan website. this is the ZX-25 race system installed on the ZX4RR. OEM filter

Wondering how to keep the o2 sensor? I believe the wire is short for this exhaust system. Will it need an adapter or extension to reach?
