The only two complete turbo back exhausts that were made for our car have been discontinued. They were made by GHL and Ion. You can still buy a Vibrant j-pipe back or a Corksport and possibly Perrin if that is still made. The Vibrant is most common because it has a catalytic converter, but the Corksport has an option for one. The Perrin is catless. I wanted a full turbo back as well, so I bought a Vibrant and paired it with the old style Corksport s-pipe.
Unfortunately you would have to get an s-pipe custom made unless you were to find one used. I would suggest looking for the Corksport that will go to the j-pipe and then pairing it with their newer downpipe that is the s and j-pipe together. Their website is corksport.com
