O2 Simulator Spacer for Catless Exhaust

[7TH_SIGN]

Going to go with a catless exhaust system like all my other cars. However this time I'll be staying on the stock ECU for a while.

Has anyone here had success on our GEN V using O2 spacers?

Thanks

I noticed on my brand the mini cat version stated for 6.2 liters and under. Not sure mini cats will work for catless. O2 sensors seem pretty sensitive.

Thanks. That's my concern as well. 8.4L and removing four cats.
