It's legal only if the sound output is low enough, and if the point at which the exhaust gases exit the pipe is behind the rear-most part of the rear-most doors on the car.
Basically, the furthest forward you could put it would be just before the Y-pipe (if you're lucky).
For info on how loud it can be, you can start here:

The following was posted on another website by an RTA AVIS (Authorised Vehicle Inspection Scheme) inspector:
My understanding for a safe and legal vehcile according to RTA rules are;
Not too loud, If sounds too loud and possibly feel that louder than legal limit then a noise Db test report is requested to be carried out.
Mounted securly and correctly with no structal engineered bracketry out of that what you would expect to be from STd manufacture specs, if mods have been done then an engineers report to be sighted (Like extractors through inner guards when fitting an 8 into EH holden etc...)
No pipes to be forward of last opening side window by at least 500mm( side dump pipes)
Pipes/mufflers not too low (4" clearance throughout entire under carriage)
Cat fitted where appropriate according to spec.
Tailpipe not to pretrude further back that a std type exhaust tip.
No holes in exhaust system at all (corrosion in pipes/mufflers etc..)
These rules infer that you're up for an immediate defect regardless of where you put that thing (if you're caught with it).
