Good question. I want to install the same WB controller on my car and was wondering where's the best place for the bung.

There's certainly not enough room between the turbo and muffler inlet. The manufacturer advises it should be approx 6" downstream from the turbo. There's no way I have 6" of pipe between turbo and muffler.

My only option is to put the bung closest to the outlet of the muffler can. Don't put it close to the exhaust tip, because your readings won't be accurate due to pulses in exhaust gas, your O2 readings will be off. Might be more of an issue at idle though?
