best spot to mount a/f senser on mcx rear mount turbo

[rx1 fern]

hi ,a buddy wants to install an air fuel gauge on his 2003 rx1 with an mcxpress rear mount turbo and we are wondering where a good spot is to install the senser .we took a look and was wondering if it should go before the turbo or at the short piece on the exhaust side .on my front mount turbo it is after the turbo before the muffler ,but mine is alittle different.let me know please and thanks .

My mcx nytro has it between the turbo and the muffler.

In front of the turbo, 3-4 inches, at 10 o'clock position.
