the ARCS is a mid pipe system with and end can. You can have the original version or the side exit GP3 system. You use the stock headers, cut it off just before the CAT and install the mid pipe and end can. Works great.
There was also someone selling just the mid pipe or link pipe on ebay which would allow you to add the stock muffler or any slip on made for the S1K. There is a thread on here somewhere about it, search is your friend.
