I look at all the 930 turbos on Ebay and none of them have catalytics on them.
How are you all getting past IM with no cat?
Does anyone have the AEM system and know if I can de-tune the car to pass without a Cat?
My list on passing hot rodded 930 with big cams:

1) Find friendly place
2) unplug and injector or two
3) on 1/8th of tank, dump a 6 pack of dry-gas into it
4) unplug o2 sensor
5) turn down fuel pressure

Finally- car will run like a bag of **** and throw out emission numbers that a Prius would be envious of.
The only problem I have ever had was the emissions computer telling me that the sniffer was not in the tail pipe because there was not enough emissions coming out.
