I've got my bung just after the collector, inside on the right sidepipe. It's used for chassis dyno pulls.

I'd bought a wide-band A/F gauge system and was going to permanently mount it, gauge in dash and O2 in one of the sidepipes. I just couldn't find a good way to install it where the O2 and wiring wasn't vixible. I still have the $300+ unused kit sitting in my garage collecting dust.
