i've had the o2 sim solution for several thousand miles. aggie46 did too, for much longer than me.

on my 135i and 335i, i had a similar o2 sim work for years with no issues, with my catless downpipes.

not sure where all these "facts" come from about an o2 sim being temporary, just to pass inspection.

i've always viewed them as complete solutions, regardless of mileage or # of inspections.
