No, not at all, you have to remember that the Turbo itself absorbs 80% plus of the exhaust sound energy (transformed into heat and rotational energy), you would be surprised...try it at least...
That could be where your difficulty lies - pardon me if I've read this the wrong way but some Mitsi's (definitely the rally cars) have an element of anti-lag built in to their mapping which gives the popping and banging sounds, otherwise the burble/pops/bangs on the overrun is usually due to highlift cams and valve overlap. On turbo cars the sound is quite different as the turbo muffles much of the noise.
As has been suggested either a straight through pipe or perhaps a change to the mapping may give you 'that' sound.
