my nova has recently developed a rather ambarassing raspy exhaust noise. when i looked under the car to discover the source of the noise, i could see straight away what the problem is. the welds round the tail pipe have started coming apart and i can see little holes round it. and when i rock the backbox back and forth, the mid-section doesn't move at all leading me to believe that this weld has come apart completely.

is this re-weldable in any way? or is it destined for the bin? how much am i looking at for someone to weld it up? how much would a new backbox for an xe nova be? or better still, has anyone got a spare one lying around for little or no money as i'm completely skint?
