Hello Mustang Works ( New to site)

I own a 1993 5.0 Mustang Conv that has some modifications. I put on new headers, high flow air filter, cat back pipes (no mufflers), new electronic ignition system. I keep getting a check engine light . The code is #31 . Which the book says is Canister or EGR valve control system. Should I replace the EGR valve or EGR position sensor ?? Or is it because I made those modifications , and new EGR parts will not shut down that code ?? Please Help Thanks
