If you have a car jack, jack the front of the car up and have a look at the flange connecting the end of the down pipe to the exhaust, if its the same shape and bolt pattern then it should just be a case of removing the bolts on the flange and the turbo end too. Then get new gaskets (from Mr Revhead) or just gasket goo (from Repco or Supercheap).
Might pay to try line it up and see if both ends line up with the standard one, if they don't match you'll have to get a new flange welded onto your standard exhaust.
If you don't have any tools etc then you'd be best to get an exhaust shop to do it for you.
