Thread: Open headers & WBO2 sensor.

  1. #1

    Default Open headers & WBO2 sensor.

    I'd like to start my engine, but it's going to be next to impossible to complete my exhaust before starting the engine. I have about 10 inches from the WBO2 sensor and the end of the exhaust collector/reducer. Is that enough to get it to run without false WBO2 readings at idle? I obviously won't be driving it this way. I just want to be able to move it under it's own power before I take it to the exhaust shop. I can probably extend it with a flex coupler if need be before I get the exhaust done correctly, but I'm not sure if that's necessary?

    That should be fine (depending on idle RPM), so try it & see.

    I'd add a temporary extension.

    Danny, it's a fairly big cam. I'm going to try to idle it around 900 RPM at operating temp. I can probably get some flex pipe on there as an extension if need be?

    Yes, flex pipe is fine if needed.
