Just picked up an 07 E63 with a set of American Racing Headers installed, no cats, no resonators, just mufflers. The smell was really strong and the sound was super obnoxious at WOT so I decided to have a set of 200 cell cats welded in. Much better IMO. I need to get the car inspected, but I'm in NYC and there's emission testing involved. I got a guy, but he says I can't have more than one monitor in a not-ready state. Right now, I got a few more than that. Based on the Torque app, is it safe to say that I got a bunch of stuff coded out? Rear O2s? SAI? EGR? If I find them coded out, and code them back in, could the ready monitors actually go ready, or will I just end up with a CEL? Any guidance is welcome.
