Since we're tangentizing anyway, I have a question about WBO2 sensors. I have the B15/P11 version of the Hot Shot Gen-V header on my car. Is the second O2 bung (close to the main cat) an appropriate place for a WBO2 sensor? I have no intention of removing the cat. Too much backpressure? Not enough heat? -- -=|JP|=- <//>< Yeah, I rock the mic like a cuttlefish...
