Thank you. As for the turbo manifold... not sure yet. I don't want to say anything else for the sake of this thread and/or my post being deleted.

The light is on because the lower 2 sensors are reading that your cats are not working correctly. In reality the cats are missing completely. You will need the O2sim to trick the ECU into thinking the rear O2s are getting a good signal which makes it think the cats are there and working just fine.

Which O2 Simulator's wiring is OK for '01 GS300 ?
There is so much information about different models. Is it possible to clarify the situation for each year model ?
Thanks a lot for your help.

I have a LMS cold air intake and a header on my 01 GS3 and the car is definitely waaaaaaaaaaaaaay more responsive off the line. The rest of the exhaust is stock. I have a NEO that is gonna be installed, then I will get it dynoed. The car is very quiet, just like stock, but when you romp on the throttle, people's heads turn! Headers are not legal in any state, I don't believe.
