Bad advice. I would definitely use one. A few years ago I was racing at an NMRA race and we were sitting around in the pits when the bottle let loose. If it wouldn't have been for that blow down tube there would have been trouble in the car. My advice is to just buy one and install it the way the rules state and you will be fine.
