i have a 06 m7 that i have installed a D&D y-pipe speedwerx single pipe and can. i now have a bog,i have a bd box but would also like to install a a/f gauge where are u guys mounting the sensors???
all of the ones i have seen have been in the muffler, or in the outlet of the muffler. i would think that the exhaust pulses would mess up the reading being in the expansion chamber
Ive got mine in the bend right before it dumps into can.. Seams to be where the majority of people i talked to recommended. Has worked great last two years.
