thunderheader o2 sensor bung plug?
About to install my T-header and have a ?. I have o2 eliminator, when installing pipe should I use a bung plug and if so what do I use(size,lenght,material,ect.). Or is it best to just leave sensors installed?

You can get the plugs from the auto parts store. m18x 1.25
I'd paint them with a rust-resistant paint first. The ones I got are all rusted out. Also, a little anti-seize on the threads before you put them on wouldn't hurt either.

I too opted to use plugs for better air flow. Not sure it makes much diff.
One reason to consider leaving the o2 sensors in is having the ability to un-hook the Power Commander when diagnosing a poorly running engine. There have been a few threads where water in the PC to ECM connection caused rough idle etc.
Now if I want to see how it runs without the PC, I'll have to re-install the o2 sensors.
