Narrow and wide band help

[lowpressure]

Quick synopsis?.

Gen3 coyote twin turbo with ford racing controls pack.

I have barely enough room for the wastegate between the header and turbo so no room for my narrow band sensor bung. Can I place my narrow band close to the turbo on the down pipe? If so, how close? I?ll put my wide band further downstream. Pipe is 3.5? x 30?

Thanks!!

Not sure why my phone added a few question marks ��

Factory upstream is a wideband. Narrowband goes downstream for cat monitoring and wideband drift (FAOSC).
