I have a '81 911 ROW with the 930/10 engine that was imported from Germany to the US in about 1986. I understand that the ROW version for '81 had a smog pump (not currently on-board but can be mounted for emission testing inspections) with no O2 sensor/computer. The exhaust system is the common cross over headers into the cat into the 1 in - 1 out muffler.
I have a couple of questions for forum members who were actively involved with early 80's ROW 911's before the cars were gray market imported into the States:
Is this exhaust that I described above the stock ROW exhaust system that was delivered in Europe? Or at the 1986 time of entry into the States, was part of the federalization process to remove the stock ROW exhaust and replace with the corss-over cat system? If it was replaced in 1986, was what the configuration of the ROW exhaust system?
Looking at the exhaust studs now, it appears that its been many years since they have touched - probably either at the 81 manufacture date or the '86 federalization. I've seen worse but these are not in great shape either.
This question may have been covered in previous messages but my archive search did not get me the definative answer I am looking for in regard to the orginal '81 ROW exhaust system.
Thanks
