EGR Cooler in CA. Aftermarket or weld?

I am going to have my oil cooler done next week. Also gonna replace the EGR cooler, but since I am subject to smog inspections I am afraid of doing the delete. I am considering welding the factory cooler while it is out.

Any cons to doing this type of delete? Or should I just go with the Sinister or BPD EGR cooler?

Re: EGR Cooler in CA. Aftermarket or weld?

I would just weld it up for visual. The emissions test there isn't based off of a smog, its visual opacity of the exhaust for a determined length of time at a certain RPM. Unless something as of recent has changed that's the way its done. It's not going to smoke more with it deleted or welded but you may want it to appear as if its still functional. Also a CEL will count as a failure in that state.

Thats what I was thinking, and I can use the money I save on the EGR cooler to buy the SCT. Is there any downside to not programming out the EGR right away?

Welding it up only stops the exhaust from flowing through, so the valve will still cycle open and shut like normal when called upon. But you might get a insufficient egr flow code.

How does one get an insufficient EGR flow code on a 6.0?? Where is the sensor that monitors EGR flow?? I am fairly confident that the EGR valve only gives the ECM position information.

It deterimines egr flow based on the MAF if it has one and the IAT in the manifold. It is just a calculation there is no "flow sensor".

So this is why the SCT tuner is used to turn off the EGR function I am guessing. Will there be a driveability problem if one doesnt have the tuner right away?

On the 6.0 no on the 6.4 yes. But with some states they will fail the inspection if it has a CEL lit up.
