EGR Valve???
What is the EGR Valve? Do i need it? What does it do? I need to remove it so i can put in my headers and i live in Orlando, FL so no emissions inspections. Thanks

You will have to delete it out of the ECM. The EGR puts a small amount of exhaust back into the combustion chamber to burn off more fuel lowering the emissions. Since I have ZZ4 heads there were no EGR passages in the heads so I had to delete the EGR. I put a block off plate under the EGR valve and took it out of the ECM so I wouldn't be throwing codes.
