Yes, best keep your back box then...
:)
However, it might be worth surfing the web to see if you can locate a back box that is straight through construction, or a performance quality back box...
Back boxes work by muffling sound by sending the exhaust around a maze of baffles. 
Less baffles would still quieten sound, but give less restriction and a nice rumble...
Its the rumble sound your after, not the roar... 

i want a nice v6 burbble when on tick over and steadu driving and when i hit the loud pedal for it to roar
Have had a quik surf, but sadly nothing listed for migs...
However, some measuring of pipe bores, and maybe something would be compatible...
But, some of the back boxes I did find were close to £200...!!

I liked the look of the Piper sports cat, almost non-existant, but meets legal specs...
http://www.pipercams.co.uk/exhaust/A cat robs a lot of power from an engine, as will any box fitted so close to the front.
What will truly give the system its best sound, and performance overall, is tubular headers (manifolds), but the mig seems a bit tight on space down there...!!
They have been done though, custom made of course...
