hey critter! Oh a weld rattling, glad it was something simple! But did the P0420 go away? or wait.. you didn't replace the main catalytic, it's still headers? Not sure how you're going to fool the primary 02 sensor with an anti-fouler. Since the primary isn't just an O2 sensor, it's an a/f (air/fuel) ratio sensor. I think it's a wideband if I'm remembering it correctly. Yup I'm full of good news!
