The exhaust is naturally connected to the turbo at the front. The downpipe is connected to the transmission bellhousing originally, but some aftermarket exhausts have the front attachment moved to the right front chassis leg. At the rear it should be originally hanged at the front side side of the left rear wheel and after the back box.

I would really really recommend an additional mount at the centerline of the car to the rear transverse chassis leg. This is where they usually hang badly.
