Exhaust shop recommendations - Brisbane?

I want to get rid of the $%^# of a system that was put on my zed for safety cert(after I made my deposit...).
As you can imagine it's the absolute cheapest system they could get.

Can anyone recommend an exhaust shop in Brisbane? The more northern the better!
