my exhaust has just broken at the flange at the back box,and it is making a nice growl and this got me thinking, can i do without back box and just fit a straight pipe to rear of car.

I don't think theres any problem with that as long you're not violating any noise laws or have any easily annoyable neighbors.
Also I've heard reducing back pressure will reduce engine wear and add horsepower. Maybe someone can clarify further?
