For all those with a CEL and no cat

I occasionally get the CEL coming on with both the straight pipe and the stock catcon, but it is only when cruising (constant speed) at about 95 mph. When this happens, I disconnect the battery to reset the ECU and the light goes a way. It is a bit of a pain, but seems to work. It's not too often that I get to run at a constant 95 for a few miles!
Anyway that is my experience with this fix.

Sorry for being too terse. 
A translation:
catcon = CATalytic CONverter
This thread is about the CEL (check engine light) that comes on when running a straight pipe (test pipe) instead of the catalytic converter, or sometimes when using a high flow catalytic converter. A commonly discussed fix for this is to space out the second O2 sensor after the catalytic converter using two sparkplug antifouling adapters (or spacers).
I'm using a exhaust system with a 3 inch downpipe and 3 inch catback. On the street, I usually install the stock catalytic converter into the exhaust system. When I go the race track, I replace it with a 3 inch straight pipe. This is pretty quick - only takes about 15 minutes. Putting in the anti-fouling spacers hasn't always worked for me in stopping the CEL from coming on.
When I drive a constant speed of about 95 mph for 5 minutes or so, I will usually get the CEL coming on. This happens whether I have the stock catalytic converter or the straight pipe in. The key characteristic is that I have to be at a constant high speed (not accelerating or decellerating) for this to happen.
Just letting people know that the spacers may not be a universal fix for all driving conditions. Or, it might just be a characteristic of my car. Does this happen to anyone else?

Two have fit on many of the guys here exhaust's from Vishnu and Buschur and RMR and HKS and have no problems the wire. It is very long just undo the bendable wire holders and reposition then bend back.
