What exactly do you mean when you say screw into the bung where your sensor is now? Do you mean on the catback itself? or on the Test pipe. I also have a mechanical o2 fix just in case. I am just a little confused as to where the sensor will go.

Will it go on the test pipe itself or will it go on the catback exhaust because there is an o2 bung on there too, pretty close to where the catback meets the TP.

Thanks!

 

If the sensor will reach the test pipe, screw it in there. If not, use the fix that you have and put it into the cat back and cap off the test pipe with a plug. Either way you go, you will need to plug one of the bung holes.

 

if you use the one already on the test pipe, you'll more than likely have to extend the wires to reach it. if you want to use the mechanical fix you already have, just put it in between the 02 and cat-back where the sensor is now and put a plug in the bung on the test pipe. either way, you'll have no CEL. it's preference of whether you want to lengthen wires or not, and like i said, not all cat-backs can run a mechanical 02 fix(like you already have) because the angle of the bung creates clearance issues with the floorpan. a plug is included with the UR pipe.

 

bung holes.....

 

Awesome i think you guys finally straightened out my confusion thanks for all the help, and yes boscoyo i will be plugging one of the bung holes
