    O2 bung install pics

    Check out these pics of the bung I just installed in my J-pipe. Looks a lot cleaner than the squre cut out methud. Used a 1 1/2 hole saw on the outside part and a 7/8 on the inside to cut holes then tiged the inside then cut a round piece and tiged the outside.

    Been doing them similar to that for a while. Your correct it is alot nicer than the square cut out that is prone to cracking. Nice Job. polished and all. It looks like it was born there. Next time try using a 1 1/4 instead of 1 1/2 and weld the inner and outer together before you put the bung in. Same outcome Its just a little easier..

    I gota do this soon so i cn get my x charger dialed in. When you say weld the inside to the outside do you mean weld the outer jaket to the inner exhaust pipe? What is the distance between the 2 layers? Could you be alittle more specific on the process?

    Thanks in advance R88

    when using a J-pipe set up the best spot i have seen and used so far is like this one! they all work fine its just ome are harder to get the sensor in and out of with everything in the hull...when the j pipe is installed this port area sticks straight up at u and makes for easy install and removal of the sensor! BET!

    The J=pipe is water jacketed so when you install the bung you need to make sure you dont have any leaks allowing water to get into the exhaust and cause you to have false A/F reading. If you weld the inner and outer sections together around the 1 1/4 inch hole you drill through the outer layer you wont have any issues. Read this it shoukl help.
