Anyone have experience with a mani without the 1st o2 sensor and no egr? Is it necessary to have these on the mani (I know the EGR can be eliminated) but what about the o2? I could probably get it welded on.. but not too sure on the point of why the mani didn't have an o2 sensor thing to begin with. Thanks.

The only way it will work without the o2 sensor is if you run a standalone ems. I'm running without o2 sensors, and using a MicroTech ems.

I have a Spool main, it doesn't have the EGR or the O2. It has the O2 on he dowpipe though. It's not that difficult to add it to a DP.

Can you have an a/f wideband work okay with the o2 sensor on the downpipe? My exhaust has one right after where you connect the j-pipe, but I'm assuming that's the 2nd one. Would you happen to have any photos of your mani w/ downpipe?
