Well I gave 50 bucks for an aem wideband, sensor and overhead mount, so i'm itching to put it in, but where can I weld the bung in at? After the cats? Before the cats? My buddy had it after his ory since he was running long tubes and no cats, just wondering the best location so I can start using it

 

Best location would be on the driver's side bank somewhere close to the manifold. Since #7 cylinder seems to be the common problem, would be best to monitor that side.

 

Ok, so weld it in before the front 02 sensors then?
