One of the vest shops in Brisbane is:
Fat Pipes Custom Exhausts
u10/1191 Anzac Ave
Kallangur QLD 4503
(07) 3285 7417
He does great custom jobs, one of my customers drove from Towoomba and called me to say he would have driven twice the distance it was worth it. I know I am going to him to have mine moded sometime in the near future.

Cheers,
