In the process of installing my pacesetter LT's and ORY- pipe. I'm only using the 2 O2 bungs on headers and tuning out rear O2 sensors since I'm going catless. I would be installing my AEM wideband. My question is where is a good location to weld the required bung for my wideband on the ORY-pipe ?
Thanks in advance guys.

 

I always install mine i. The header before the flange to the ory. Reason for that is just incase a leak is developed at the ory flange. Having the bung before that eliminates that possibility.

 

Yea I was thinking about that too.

 

You could use the rear bung if you keep the collector leak free. I had limited space on my setup and used the front bung and then used my controllers 0-1v output wired to the factory o2 connector.

 

The closest you can get it to the exhaust valves while still capturing all cylinders is optimal. On some setups when I plug the wire into my cable to capture wideband data, I have to tune taking exhaust flow delay into consideration. Depending on how far back the sensor is, by the time the exhaust gets to the sensor, RPM and/or manifold pressure may have changed. Of course this is a non-issue on a loaded dyno, but most of us only have the street to tune with

 

I run mine just after the O2 sensor in the 3oclock position on my pacesetters. driver side
