Thanks for the response fily.
The headers were dirt cheap. No brand given, but they are definitely made in China, and the parent company sells products on Amazon under more American-sounding names like DNA Motoring and Auto Dynasty. They were only $138 for the pair, and I'm still doing the write up on them. The bung is welded close to the correct location, but it sits at an angle that is off by at least 10 degrees. Not surprising since I had to redrill the mounting holes and gaskets, one of the O2 sensor bungs requires relocating the transmission dipstick, and only the tubes are stainless steel. The rest is mild steel. That being said, I was on a budget, and the X is back on the road.
I considered doing an EGR delete, but I was worried about losing mileage. If the computer detects too much oxygen it will add more fuel to the mixture. This is what you would expect if the cylinders are filling with 100% air instead of a portion coming from the exhaust. ECU isn't throwing any EGR codes with the temporary delete, so maybe I'll make it permanent. If the early models didn't have it, then I probably don't need it.
