HELP DPF on D40

[APTUNING]

I am currently working on a D40 trying to disable DPF mode and dispute assurances from my programmer it is proving very difficult but we are working through it.

I had a customer ring up with a brand new STX550 V6 and we are looking to put a power file which I know we can do with confidence. HOWEVER, he is looking to also replacing the exhaust. Suggested a larger free flowing exhaust upgrade which we could still tune.

He is now being told by a tuning box supplier that Nissan has disabled the DPF in the most recent models so can be replaced by any exhaust.

Is this true? I have my doubts, if it is disabled wouldn't it clog up?

If it is true then easy for me to do

Owner just been under navara, can not find DPF, wires or sensor so pretty much answers that i guess

Only the auto has the DPF, and to 2010 I believe. So 2011> auto's don't have em.
