Ford AU 6 cylinder exhaust

[russky]

Hey,

Ive just been thinking of fitting an exhaust system for my AU Fairmont, however, its not a cheap job, and really dont want to get it wrong with a wrong system. What im looking for is something of Italian v8 nature, quiet at idle, but screams its head off when revved hard. The high pitched sound dont think is possible to achieve, cos of engine, though have heard once a new XR falcon flying past with something similar to maserati sound. Does anyone know whats the best approach to tackle in order to achieve what im trying to? Quiet at idle, while a good sound at highish revs? had a muffler done before, but quickly refunded my money, cos it sounded bit loud (would not have appreciated it if i had a headache), and not to my taste. Will a complete exhaust system be necessary to quieten the sound? or just muffler of some sort?

Any help would be appreciated,

Alex
