So I am by no means ignorant so maybe I should have been more clear with my response but my Coupe is the same way. EGR is installed and connected to the ECU but all the rest of the emissions has been long gone. With the tune on the previous motor it passed Houston emissions testing with flying colors with only the catted X-pipe.

OP asked if it was needed and I simply stated it was needed in order not to trip the CEL. Here is a really good thread on this:

For those that have deleted their EGR valve

I have the heads off and decided to delete the EGR, but I want to do it right. What all is needed to successfully delete the EGR? Thanks guys/gals.

EGR on '94/'95 cars comes from the cyl3 runner on the passenger exhaust header. You don't need a GT40 lower intake with that passage, it's legacy from the FoxBody cars that pulled it through the intake. SN95 5.0s picked it up externally. The only problem with the non-EGR GT40 lowers is that their ports are a little bit smaller. This can be resolved through porting.
