Sorry I'll be a bit more helpful now. If it were a cat back I'd say do it on your drive, turbo back you need it on a ramp really.
2 of the nuts on the downpipe are pretty awkward to get to and you could easily end up snapping a stud.
I chopped my standard exhaust just before the rear beam as it's one piece from the cat to the back box. It's either that or dropping the rear beam, I went for the easier option.
