    I am getting ready to order my TTI headers . The Part number is 440-200. I have the option of having the O2 bung on the Header collector or on the reducer/adapter. Any preferred spot?
    I have not been able to find a pic. Maybe @AndyF has a pic?

    Also what size reducer adapter? It is in a 73 scamp with a 512 ci RB .
    Choices are 3.5 to 2.5, 3.5 to 3.0 or 3.5 to 3.5?

    As for the O2 sensor, I have mine installed and would install it in the reducer where the exhaust from each of the cylinders will pass over it. Make sure it is installed in the top portion of the pipe.

        i will eventually go with an EFI system and was leaning towards the bung being at the collector. I'm interested to hear reason to go otherwise....

        IF IN THE COLLECTOR , IT CAN GET ITS INFO FROM 1 OR 2 CYLS ., NOT GOOD, PUT IT RIGHT AFTER THE HEADER FLANDE OR CLOSE IS BEST , DO SOME RESEARCH . Also 10-2 oclock position .
