I just got my MACs, they were used and there is only 1 rear O2 bung. There's supposed to be 2 but the Y-pipe was custom done to fit a cat with straight pipe in place and i guess they got rid of one of the bungs. So my question is, can I run my exhaust with only 3 sensors? 2 in headers, 1 in y-pipe. I guess i can still hookup the extra O2 sim but I'll have to mount it somewhere. Will that work? please help guys!

the B2S1 B2S2 o2's arent needed, i'd remove the o2 you go in the rear bung, plug it up, and run 2 o2 sims for the rear.

yea i gotcha captain, so where is a good place to tie the O2 sims to? does anyone wrap them in plastic so they dont get wet?

I just hooked mine to the existing holders on the transmission. The ones I used to have had waterproof covering on them already.

look and you will see that one of the front o2 bungs is on the exhaust manifold so there is actualy a total of 4.
