3.4 swapped Cross "under" questions and upstream o2 sensor results?
Been doing a bit of research and other then problems with the clutch slave, fuel lines, and offroading clearance not many people have had a problem with running the crossover under the trans once you re route everything.
I already have my 3.4 installed with a thrown together crossover but i'm pretty sure its cracked somewhere and would like to improve on the design/flow without buying a header and cutting it up.
Do not have a rear o2 sensor already so that wont be a problem only thing i'm worried about is the fuel trim readings from the upstream o2 sensor affecting the way it runs.
No smog here in Oregon.
Jasond did dual exhaust and had the upstream only reading off the driver side bank and seemed to run fine with -10 ltft

Tons of info on the factory design x over but not to much for the other.

Swapped under and running o2 only in driver side. She runs pretty good ;-)
I run two 1 7/8" vbands on either side of the trans, and then one more before the turbo so I can unbolt the exhaust it to do trans or engine work.
