Exhaust Systems in Brisbane

Anyone know a good but reasonably cheap exhaust shop in Brisbane. I want to get a full set of extractors & sports exhaust (2 1/4 inch approx)for the Viagra - the 30 inch wheels are sapping a bit of power, and I've had the exhaust manifold cracked and welded a few times anyway so it currently sounds like a diesel.

That's the only bloody thing that's broken on it so far, so time for a new one - but where do I go?

Also is it worth getting that exhaust tape/bandage stuff arto try and prevent water and mud splashing on the hot metal and provoking cracking - any ideas?
