I apologize in advance if this has already been asked. Does anyone know if there is a Flowmaster Super 44 for the 2013 Sport 1500. If so, do you know the configuration and/or part number. I ran a search on their website and didn't come up with a good answer, just a form to fill out that says if something becomes available they will email me. Find it hard to believe that none of the existing configurations work. Thank you.
