Looking to install the Akrapovic Sport Silencer on my 2013 STS to replace my OEM muffler. Just wondering how involved it is. As I understand it is just a simple bolt or "slip on"? Also does any tuning need to take place with the computer to compensate for the new muffler? I saw one forum member indicate on a thread from a few years ago that this is not necessary but I just want to confirm what I would be getting into
