True Dual question
so I'm going to custom make a true dual exhaust for my car I was wondering am I going to need 2 02 sensors or just one? I'm not sure because there isn't going to be a spot where its all one pipe.

Check out the racing beat website. On their true duel headers they run one sensor on the front rotor housing pipe. I recently purchased a true duel header from a guy that was running a carb setup and all i did was machine a bung and weld it in for my car.

You only need one for running the engine in closed loop mode. However, if you use the O2 sensor for tuning a standalone EMS with an individual fuel injector trim function, then two are better because you can tune each rotor individually.
