for states with emissions, can hondata or Ktuner permanently keep engine lights off with catless downpipes?

Hondata no longer allows this, if the light comes on, they will not allow you to disable it. They are no longer allowing you to disable CELs on emissions systems. EPA is cracking down on companies who offer products to defeat emissions, even if its for off road/race use only.

Ktuner still allows you to bypass the CEL.
Is Hondata doing this on previous versions?like the 8th and 9th gens.My last Civic was a 9th SI that had a catless Downpipe,of course VitViper tuned with Flash Pro and also the CEL issue was disabled.
