ok i got the blocker plate and im going to put it on in a few min. when the engine cools off. But i have been wondering.. Where does all the exhaust go that is being blocked off? just back into the exhaust or what? and all i have to do is slip the plate in right?

Dont you have to fool the computer also? I have my truck apart right now and want to block this, but dont want any error codes or it running funny.

No cons that I know of. There is a possibility of codes showing up. They say that some trucks are different than others. I put one on my truck and to this day I have no codes. Have driven about 500-600 miles since the installation. I did notice that my truck smokes a good bit less. I don't know if it is just me or that the egr blocker plate keeps it cleaner.

Please clarify for me. On a LMM, if I install an EGR block plate, I won't have codes. However if I install a downpipe that gets rid of the egr and heater, I will have thrown codes.

So if you put in the block plate, do you leave the egr connected and it acts more or less like a politician - sits there, but essentially does nothing? Or am I missing something?

From here the block plate seems like a great short term fix until funds allow for the better flowing pipe replacement.
