Those Diesel pickups did not have to meet new pollution requirements.
Small passengers cars in the around 2005 had a whole new batch of regulations adding in the EGR valves and DPF which are the culprits behind all the destruction and carbon deposition.
A diesel without a DPF and EGR valve is great...but illegal now a days.
They reduce emissions a boat load (not really, since the DPF just dumps everything out at once instead of all the time, but hey all that matters is what happens during the inspection! lol) but have a serious detrimental toll on your intake and exhaust manifolds.
