I am hoping someone has the answer. I have been looking at changing out my MPD 364.5 SXE turbo and the way I am going is requiring me to do a 2015+ upgrade kit. All of the upgrade kits appear to have a right side exhaust manifold in their packages. I have looked up the part numbers through Ford for the manifold and they all appear to be the same part# from 2012-2017. (I looked through the 2017 model year since the turbo they are now using for the 2015 is from the 2017 model year.) So, is it necessary to change this out, if so, why? Also does the 2015+ require new up pipes? I am having a hard time figuring that out as well. I am getting all these parts through Ford since I can source them cheaper than through other companies that have a "kit."
