no it wont blow up :-)
the cel code will be P0420 catylist efficiency as the ecu monitor cat in header and you now have no cat.
your cruise control also will not work with this code and cel active.
you can reset with battery removal or by using an obd tool or scanner like torque android app on your phone and a elm327 adapter.
but its going to keep comming back till you get a tune or you can try a 02 sensor spacer in the REAR 02 sensor
like this

to try to trick ecu that their is still a cat in header, but they dont alway work 100%.
as the other guys said tune is best option
