It can be done with some cutting and welding. The exhaust shop will also be able to provide hangers for the passenger side. I had a 02 GT exhaust take off's on my 96 that I later changed out mufflers, but still used the pipes. Do yourself a favor and find a hole in the wall mom and pop exhaust shop to install it for you. If you take it to a big chain like Midas, they will try and rape you on the price. I was able to get mine installed for $75, but that was with no Y, X or H pipe, true duals.
Good luck!
