i would not remove it. You're going to totally **** your EGR system, and you will not pass emissions.

my egr system has never worked, the solinoid that controls it is no where to be found.

i would try and get it back in operation, it's necessary for the engine to run correctly. Pick up a solenoid at your local JY

If you are set on eliminating it, here's a diagram to help you figure out what hoses to keep and which to plug. Definitely keep the ones going to the egr valve and the map sensor.
