Ok wondering how much for lowerin eexhaust using superlows and a basic 2.5 exhaust system? Or is there anything better?

Finally where can I get these done for good prices in the Gold Coast area, possibly Brisbane?

If its a six the exhaust will be around the $300 mark. If you are only gonna put the springs in (no new shocks, camber kit) then lowering should be about $450

do the exhaust yourself...bit fiddly to get it into the right possition and get the old rusty bolts off (may need to cut the pipe in some spots) but i am sure you could pickup the parts for $150...its what i did, needed to fiddle a lot but got it right eventually. The problem on EL and EF's is that you have the sway bars on the diff, they tend to scrape on the exhaust if it isnt placed properly...and then you find it will scrape on the bumper bar if you put the exhaust too high, both causing annoying knocking noises...

so unless you consider your time worth more than $150...do it yourself.
