D40 Series4 Zorsts

Gday Fellow Navarians & Navarianettes

I have a 09/10 manual Series4 140kw ST-X Manual. Could someone please clarify which models have the DPF, because if mine doesn't, which I don't believe it does, I'll be running straight pipe from the turbo back quick smart. I just remember 2yrs ago I was reading bits and bobs on here and other general 4X4 forums before I purchased it and remember reading stories of horrid performance??? Something to do with pre and post pressure sensors in the muffler???

Anyone done this before?? HELP PLEASE! As an ex diesel fitter and owner of 3 MQ/MK Patrols years ago, the mufflers were the first thing to be removed, so Im quite embarrassed to be asking this, but Common Rail technology and what not has me totally baffled

I've fitted straight thru pipes to my 2010 K108 Kenworth running a Cummins EGR Signature with FANTASTIC results.... Performance when lugging below 1400rpm , 50'c cooler Pyro temps and a shit eating grin with the windows down at 1500rpm dragging 125tonne on the float! lol

Yours is manual. It doesn't have a dpf. Only autos carried the dpf

So, off with the muffler it is? lol

I'm pretty sure a lot of navs on here are running no muffler. If its a manual then there is no dpf. Meaning you can run what system you wish. I have a d22 2.5 and hopefully soon to rip my 2.5"pressed bent system for a 3" stainless item with only a cat and tornado resonator. The rest is all straight mandrel pipe

Is this based on year model? Or do all manuals have no DPF??

Cheers.

I'm pretty sure all manuals have no dpf. I could be wrong but I'm pretty sure its an auto only thing. In saying that it didn't come in all autos

hmmmm..... project zorst, coming up

to confirm no manual d40 ever came with a DPF, only the auto 127/8kw engine had them, the new 140kw auto dosent have it

The dpf is pretty dam easy to spot if you want to look for it. It came in some autos but not all. UK surprised Noone with a d40 has jumped at this to back me up. Goodluck
