Have a dilemma here, as some of you may know, I plan on putting a cutout before the cat for use at the track.
Now, I am pretty certain there is an O2 sensor after the cat, have also been told that there are 2 others, one on each header.
Now, I would be bypassing that 3rd one, so are there any problems with doing that? Do I need O2 sims, etc. I don't think Magnus uses sims, since he seems to rely on O2 readings to tune his car, so what's up?
Later & thanks for the help.
