I have my exhaust all apart except for the factory headers. I have 3 bungs per side totaling 6. The factory mids have 2 O2's per side totaling 4. In reference the front is the O2 closest to the header. With the new JMB mids the rear has 2 bungs and the front has 1 totaling 6. I have 1 wide band guage and 1 extra bung for tuning purposes.

I assume the front 02 goes with the front bung. My question is do I use the rear factory O2 sensors and if so which one of the rear bungs sould it go into, the furthest away from the header or the middle one? Also JMB kit comes with 18mm double threaded risers. Do these risers go with the rear 02 or the wideband guages?

Open headers sound soooo good.:evil: I had to start it up for a sec without any exhaust except for the factory headers. I had a few neighbors ask what the hell was that.:rock:

I plan on finishing up tomorrow with your help and I'll post a sound clip with the electric cutouts open and closed.
 
The front O2's go in the front. The back O2's go in the next set of bungs. The "risers" are O2 sims and are to be used on the rear set of O2 sensors. You need them there to keep from getting a CEL on cat efficiency or some such code. The extra bungs are for accessories.

There is 1 thing Brad didn't mention was when he started up the truck with open headers he scared the crap out of himself. :rofl:
