Going FI so need to add O2 bungs. Got a good idea where I'll put them but was wondering if anyone else has already done this and where did they put them....on one header or both. FI setup is a ProFlo4.

Gotta get these on so I can mount the headers for the long haul.

Thanks fellas.

Mine is on the inside of the left header 2 1/2” from the flange. Used it with the BDS system & now for the A/F gauge. Here’s a crappy dark pic. I’d have to jack it up to get a clear shot, but you should still use it for a reference.

I'm not too sure how correct it is. But when I get around to redoing my exhaust this is my plan for the end of both my long tubes.

I know exactly where you mean. Thanks! Whats the BDS system?

But you'll only need 1 O2? Wasn't sure if a dual setup would use 1 or 2 sensors. I'll have a crossover pipe back a ways.

Im not too sure (was also hoping to see the answer here) if I would need only one total or one each header. I haven't gotten that far into it yet, just bought the parts because they were cheap at the time. And I figure those collectors are a simple way to add the būngs.

I plan on doing an H pipe as well, probably behind the T-case. And the sensors will be mainly for carb tuning until I go F.I.
