Did anyone install headers in their S without a cat? ("testing only" of course!) and had to deal with engine error codes?

I believe u get an engine management light that comes on but I've also heard u can get your ecu programmed to suit no cat and to turn the light off

Running with post cat sensor disconnected will not through up a light or put in limp .
All it will do is registor a fault code in the memory P0036 as the heater circuit for the lambda is disconnected (so what)
