The plan is to hollow out my primary cats, leaving the stock chamber in place. I then have to drive 370 mi (6hrs) to the dyno shop in order to tune the vehicle and remove the anticipated CEL-Increased Emisions fault.

My questions are:

Will there be any long term damage to any part on the vehicle (o2 sensors?) driving for the extended amount of time with a CEL?

Worst case senario, car goes into limp mode. Can I drive that distance in limp mode?

Thanks in advance for the help.

You should be ok...I just wouldn't go WOT. They will reset the ECU for you after the tune.
