I dont think ZA bothered with emissions until about 2005 :-) BMW probably used the same ECU with software differences for with/without CAT.

Ill'd take a look on your VIN in realoem and that is exactlly what exhaust system installed in my car, parts# 18101728445.
Realoem give a wrong info on my VIN. By the way the car is US version shipped in the Philippines.
