Maybe you have a point there, but since we haven't any clue let me do some

The pressure at one side is high anyway, namely the backside of the ship.
Adding some extra engine walls may increase the pressure but also makes the
efficiency better, since the first extra walls will be at the side so that
the particle stream is more to the aft.

I assume that all the particles will be ionized so that we can make the
walls of magnetic fields. If this doesn't work, I'm not sure what would,
since the temperature of the particles would be very high (1E6 Kelvin?).

Another way to decrease the pressure is simply to add less power (which is
the smartest way, I think). So then the amount of particles goes down and so
does the pressure.
