Be worth the crap to install the Nox filter anyway, and not worry about it being plugged up?? Which leads me to another question: which one is the DPF, the long can or short can??

The only place a cat, DPF and NOx filter have value is in the garbage. Unless your engine is programmed to keep them clean all they'll do is plug up in a few weeks and kill the engine with backpressure.
