Lots of guys pass without DPF, just depends where and the inspector. Some are too lazy to catch you or just not knowledgeable enough.

It is illegal to modify exhaust on any vehicle driven on highway. The only time you can modify exhaust is for race applications.

In the county I live in PA, diesels are exempt from both visual and tail pipe emissions. For now anyway...

Only the LML has it and the Urea is removed also. The only tuner that supports this is H&S.

LMM only has DOC and DPF, EFI Live custom tuning is the way to go with this platform.

DOC isn't that the urea injection?
No...

DOC - Diesel Oxidation Catalyst
SCR - Selective Catalyst Reduction (Urea)
DPF - Diesel Particulate Filter
