What emission system do I have?
I have an 07 2500 Mega, 6.7L w/ manual 6spd, 4x4
I have been told there is an 2007 and 2010 emisions system.
It has no Bluetec badging, and the exhaust system is as follows starting at downpipe back. End of downpipe is oblong shape an has a heatshield? around it. Then there are 2 sensors (O2 and ??) at 10:00 and 12:00, then a large bulge, presumably the DPF, 2 more sensors and a tube to transmission, and another bulge (cat?) another tube, then one small sensor, and last, the muff.
Lots o' crap to be on an exhaust system.
Recently required a turbo change after 100 miles of CEL on/off/on/off. Never gave me any changes on OH display.. Just "SYSTEM OK" if the system was ok, then why did my turbo have 1/2" of soot in it. I could smell the truck regen from time to time, but never any messages.
Any recommendations, or info would be helpful. Now running w/ EB 100% of the time, and no more Lucas fuel treatment.

You have the Blu-Tech system. Goes CAT, DPF, then NOX filter. DPF has a back pressure sensor before and after. I'm guessing that's how it tells the ECM to go into regen.

Thats what I figured. Thanks 06Ram2500.
Soon I will be adding an Edge Insight to keep a better eye on what my truck is doing, b/c apparently the OH display doesn't tell you crap.
