The disc for the blow down/pop off valve will allow the bottle to release the nitrous into the trunk area. But that is not allowed in the passenger area of the vehicle. That IS not legal. BLow down tube only allows that same blow off valve to release the nitrous outside the car into the air.
If the bottle pressure is too high and the pop off valve don't work, the blow down tube is worthless and wont matter anyway!!!!!! If all is correctly installed that should not be an issue.
