Ok so first off, I live in CA so I have to smog my new duramax every other year.

I just got my first diesel, 05 LLY, and is like to delete the egr. Problem is my understanding is the smog test on diesels is mostly a visual inspection so if they see the egr components gone I’d fail

My question is, if I get a new up pipe that is usually part of the egr delete process, can I put a blocker plate on the egr end and leave that assembly on the motor to pass any visual inspections? Or is there more to it that I’m missing?

Unless I'm mistaken it will throw a code with the blocker plate (and doesn't that also make a taxifornia vehicle fail inspection) With re-tuners running for cover with EPA fines,, it may be hard to find someone to write the tune on a California truck.

But i'm no expert' hopefully others will chime in o rPM you better ideas.

I ask because I have a down pipe and full exhaust I’ll be installing soon and since I’m in there it would make sense to do it at the same time. Everything I read says to get rid of the egr but I’d still have to pass smog checks.
