Hi, would i be able to decat my stage 2 r tech eddy and then drive it to r tech to get tuned out?

GVK:
Can't see why not... you'll just get an engine light on probably with p0420 code for cat efficiency.

Yep. The ECU doesn't really care about cat efficiency and will only affect drivability a tiny bit, but it has to throw the EML by law.
