EGR Valve replacement

I need to know if there are any tricks to getting out the egr valve out of a 01 cougar ZN. I need to take the egr pipe off with it and that goes all the way down to the exhaust pipes, looked like it came out of the exhaust manifold, and it doesnt look like I have much room to take the pipe off from underenath, and I cant manage to get the valve itself away from the intake to just take that off. they have to come off as one, and it doesnt look like thats enough room from top or bottom to do this. if anyone can tell me if I have to take off this, that and the other thing just to get this out or is this just going to be the biggest pain in my ass. thanks in advance
