exhaust wont be causing it to stall

run a faultcode reader for faults

also worth throttle bodie clean

also check boost pipes for splits and leaks, could also be a faulty maf

as suggested try cleaning the throttle body, also coolant temp sensor used to cause stalling at idle when it went on mine.
