Opinions for o2 sensor location!

Doing a lot of fuel tuning work to a customers car(previously dyno'd near 450whp on cis) and installing an o2 sensor...The rear muffler appears modified for 2 tail pipes and not sure which brand??

Problem is i only have a 3 inch space before i enter the silencer box and i was informed by the customer that CO readings prior to me receiving car were somewhat different from each tailpipe!....

My opinion was to mount on the left hand pipe near exit of silencer box as i think it would probably get fried quickly just after the turbo before it enters the box..

Whats you guys opinions?


Although the weld looks pretty neat,this tail pipe may be added on to silencer box for cosmetic reasons????


And where i thought location may be best?
