What would the consequences be of running with just the passenger side backbox? You can shout me down for changing the aesthetics of the car, but for performance, what would be achieved by replacing the standard setup for a single box system.... and would the bore size need to be increased a little to compensate for this?
PS - I love the sound of the crackle from the xpowers - i'd love to get that noise..... but much louder

Thanks.
