Thats correct. Nitrous can be installed in your car, as long as the nitrous bottle is not hooked up to the end of it... everything is a risk though these days. Lowering a car too low is illigal, so is getting wheels 2" bigger, and so are loud exhausts to name a few. As long as you dont act stupid your very unlucky to get caught. But in the end its your choice, best bang for buck mod and i would definetly reccomend it:) Specially for a NA.
