Using O2 sensor with redtop headers on a greytop

NCMR2 · 07-21-2010, 08:42 PM

Hello again fellow BEAMS people. Obviously there is no bung for the O2 sensor on redtop headers and I have a set I want to use on my greytop to get rid of the cats of course. I do have a flange cut to have a b-pipe welded to. The guy who does my exhaust work is good, he just needs to know what to do.

I have heard of some guys running without the O2 sensor hooked up, but also seem to find people having issues running without one. Also, if I do need the sensor, will there be an issue using one on the b-pipe I will have made? I already have a decent muffler set I will be welding the b-pipe to with a flex pipe somewhere in between it all to reduce vibrations. I plan to merge the two 2" pipes off the header flange into 2.5" piping back to the muffler, followed by short 3" piping to a 4" tip. That setup is close to what I have been using for a while minus the redtop headers and a flex pipe.

What would be your advice and experience with a setup like this?

Thanks!

Weld the o2 bung up and mount the o2. You can order a bung for an o2 with a flange.

Ask Aaron at Lithia about it.

does it matter where on the b-pipe it is? like closer or farther away from the headers?

nope, just has to be before the cat.
