I know that for my 04 that has duel exhaust but runs both tailpipes out the left side there is this http://www.pfyc.com/pc/GT5009/GTEXH/...+2004+GTO.html

You can cut out the opening using thier template and insert and run your own piping over to the other side. you will also need to attach a hanger underneath for the right side.
