Hi, I just completed doing a SRT hood upgrade to my 2014 Overland. It is really easy if you can find a good painter that can match the paint without during blending on the fenders. I done all of the SRT hood upgrade myself except for the painting of the hood. Mine is black (PXR) so it was really hard for the guy to get the hood to match, but he did and it looks great on my Jeep. You cannot use the regular hood silencer that is on your regular hood. I have listed the parts below that you will need. You can reuse your striker hood latch, hood hinges, and hex head bolt that holds gas prop for your hood. I have attached a few photos of mine. If you want some of the underside just let me know. Hope this helps.
