Best EGR "Stealth" By-pass or Delete for Emisssions-Crazy States like CA?

I really want to dump my EGR--realizing that it is not possible as I live in Cali and will soon be faced with Diesel emissions testing (never had to in this state before), I am thinking about getting as stealthy a by-pass or delete as possible. Anyone have any suggestions? I don't know exactly what the inspection will be like here, but I imagine that the smog station guys won't really kknow what to look for when they pop the hood. The tail pipe sniffer will be something else, of course... TIA!

I share your pain. I've developed a "wait-and-see" attitude as to how exactly the smog chek will be implemented, and by who. Maybe even go through the process myself once before I try to get sneaky.

I'm in the same boat! The last thing I need is to fail an emissions test because of something visual.

The other thing is most blocks or sneaky pipes might or might not throw a CEL and the only way to stop it is to run an SCT file. Will having an SCT filed loaded in the vehicle cause it not to pass? So many unanswered questions.

Wow. Is there such a thing as an EGR by-pass that does NOT trigger an OBD/CE warning? We're screwed...

I'm sure there is going to be some model specific diagram for them to go off of. Since there will be no way for them to check the actual EGR flow, we should be good if it all looks like it is there.

My original plan was to buy a "sneaky pipe" or weld up the oem pipe. Then get an EGR plug to replace the EGR valve. Then just keep the OEM EGR valve plugged in, but zip tied to the side out in the open, hoping this would not throw a CEL.

Now my question has been, if you have only a "sneaky pipe" and the EGR valve still installed and plugged in, will the truck throw a CEL? I have not been able to get an answer on this.

If it won't then when inspection time comes, uninstall the EGR plug and reinstall the EGR valve and you are back to looking stock!

What does everyone think?

Ok, and you would also need an OBDII tool to remove the CEL... That's sort of what I was thinking--be sneaky, leave everything looking stock, and crossing my fingers...

what does your obdII test consist of? if you wanted to be real sneaky, take your dash cluster out and remove the CEL light bulb. It will still show up on a diagnostic scanner, but not on the dash. Dont know if this will help..... not in CA.

I think they actually plug something into the OBDII port--not certain, though.

If just by adding a sneaky pipe while leaving the oem EGR valve in and plugged in does not trigger a CEL then we are all good. Now all I need is an answer to this.

It is easy to R&R the EGR valve. So if no CEL with just a sneaky pipe then reinstall the oem EGR valve and go for inspection. Then when you get home remove the EGR valve, reinstall the EGR plug and load in a SCT tune. Done!
