I just got an aem wideband setup and plan to instal it soon. I was wondering what the best option is for installation. Is it possible to use the oem bung and use my ap to turn off the cel that develops? If not is there a good place to weld a new bung into the factory exhaust? What's everyone else doing when they put a wideband on a stage 1 car?

 

I originally had mine installed using the factory spot, and I ran the stock o2 sensor underneath the passenger seat and wrapped it in aluminum foil.

I eventually welded a bung to my test pipe.

 

I just got a bung installed - about $65 for the muffler shop to do. It was dead easy for them... they didn't even need to remove the downpipe. Quick, simple, cheap.
