wideband

  1. Hyundai Genesis Coupe Performance
    Where to mount my wideband AFR bung? I removed my stock downpipe from the turbo back to the end of 2nd cat. I'm replacing it with a 3" SS Hi-flow catted downpipe from CP-e. Like most of my other mods, I've had the parts just waiting in a box for me to have enough time & be up to the challenge...
