I wonder if that DPF is EPA or Carb approved? No sense in spending $$ for a DPF if it does not work as well as the OEM unit. BUT if it does work that may be a low cost solution.

The DPF's for Light Duty trucks (Modular DPF's) are refurbished OEM units that have been modified to be serviceable. Clue: there is a $300 core charge on them.
Tequila, I'm glad you posted that info, as I had recently found all that myself and had intended to post them on an appropriate topic or start my own. Like most 2008-2010 light duty Diesel trucks, mine has a DPF, but does not use DEF. If/When I'm faced with either replacing or cleaning my DPF, I'm going to give cleaning it a try. The cost is about $800, plus about $250 for the service kit (adds flanges and gaskets so it can be taken apart) plus the labor cost of removing and replacing the DPF.
DPF cleaning is done routinely on heavy-duty Diesel trucks and that includes the 2011 and up trucks that use DEF. The big trucks have an advantage: their DPF's are designed to be serviced, meaning they can removed and separated easily from the catalyst section. Ours are designed to be replaced, probably to save manufacturing cost. The OEM fix for a Light Duty Diesel DPF that needs cleaning is to replace the DPF and catalyst as an assembly.
I've talked to the local shop that has one of the
Enviromotive DPF cleaning machines, and they told me that they have cleaned a few Light Duty Diesel DPF's. They also said that if you aren't going to hang on to the truck for a long time, you don't HAVE to buy the service kit. They can separate the DPF from the catalyst, clean the DPF, then weld it back together. You probably won't be able to do that more that once though.
If your truck has a DPF, it will eventually need to be removed and cleaned, or replaced. If your truck has some warranty left, you may be in luck. If not, you'll probably be wondering if there is a cheaper alternative to replacing the entire thing.
