I was about to recommend Pypes... give them a call/email to find out. Or, you might be able to figure out the location of the exit by looking at the stock pipes on the rockauto website (and clicking on "info").
I just put a pypes set up on my GTO convertible. It installs easily unto the existing mufflers and tailpipes. On this one I just used the x pipe kit on my other one I used x pipe with dumps and electric cutouts. Both are great. I love the dumps but the wife not so much.
You can buy a header kit and a couple of ten foot exhaust pipe tubes in stainless steel or settle for mild steel and take just the mild steel header kit to one of your local muffler shops to have them weld up a full exhaust system from front to back. Labor will be the most expensive part of this operation which is why I recommended stainless steel which will last the life of the car. Stainless can be MIG welded with the proper wire but it is better TIG welded. Additionally finding a TIG welder at a muffler shop will take some investigation. Look for a couple of Harleys parked out front. That means they are used to working on stainless steel exhaust pipe.
I had a full stainless exhaust including a custom header made up to put a BBC in my Impala all the way out to the rear Bows Tie stainless exhaust tips.
