Ima get some off road H pipes and a "cat back" system to go behind it cuz we've banged this stuff around and welded it down a couple times and it's still just a beat up and overall shaky system. It works, but it's kinda dumb.

My question is about EGR. Can I just stop the inlet at the intake manifold and let the EGR valve hang around by itself? Is that a better way to keep it from confusing the car as to whether or not there is an exhaust problem going on?

 

you can leave the egr bolted on and elec connections disconnected and vaccum lines plugged, ecm deletes function in such cases, it will not pose a problem
