How is it useless if the front cylinders are the problematic poppers?? Most header company's put the bung in the crossover right before it meets the rear bank. Like W-Body Store for the actual 02 sensor so it only reads off the front. Unlike factory you get front and rear all in one. Yes you could crawl under the car and put it in downpipe exit but why if there is an easy access above?

Dude any wideband instructions and/or installs you see never have half of the engine to accept that as the engine AFR reading. Wbody store just did that for a unknown reason
