Funny you say that as I purchased a generic DPF delete kit from Mother Russia (where nobody cares about enriched diesels spewing black goodness into the air).
Basically it is a black box that sends a slightly varying signal from the bypassed pressure differential switch back to the computer so the DPF can be eliminated altogether or "test tube" fabbed to fit where the media went into the housing.
I haven't gotten around to fitting because of life and the fact that I still need to puzzle out how to integrate the bypass into the harness and I don't know if Kioti's ECU is smart enough to eventually question the signal from the pressure differential.
Elsewhere I read one report that Kioti's ECU didn't even care if the pressure differential sensor was DISCONNECTED period. That same person had not removed the DPF media. Anyway, you might want to mess around disconnecting the pressure sensor and removing the media just to see what happens. Please report any result be it good or bad if you pursue this.
