If I wanted to fit just 1 single O2 sensor bung right in the middle of the rear section of the collector( 2-1-2) where the 2 link pipes separate and feed each muffler. I'll need to know if there is enough clearance to screw in my O2 sensor without it fouling against the rear suspension relay arm or anything else hanging around there.
Can someone please measure this area to give me an idea for clearance please???
I'll try to find a pic of what I need to give you more of an idea.

I want to place the bung in the rear of the collector but I just need to be mindful of the relay arm from the rear suspension.



Photo above shows their may be enough room but it would be nice to get a measurement for clearance.
I have to allow for a bung to be welded plus the O2 sensor. So approximately 4" (100mm) total .
I would have to be mindful of the angle the bung is welded at too.

I don't think you will have the clearance you need. Its a bit awkward to get a good shot but it should give you a good idea...
cheers,

Excellent thanks for that..
I knew it would be a tight squeeze and I'm thinking if I can get the slight downward angle right when welding the bung I may get the clearance needed as the relay arm pivots upwards with the swing arm moving upwards.
Are they the std dog bones your running Bane???

With the O2 sensor screwed into the bung, the tip of the sensor sits just inline with the edge of the bung.

Just 2mm shorter dog bones.
