I didn't realize DME reflashing removed the readiness monitors, I'll have to look into whether I would fail my VA inspection. I'm still really curious to know if I could cut out my existing OE cats and have them welded into section 1 of my exhaust...never got a definite answer on that either. At this point it all seems like too much work just for new headers.
