Welcome Swift-Tee. Have no dought you will enjoy and gain useful info here from a friendly team. Best of luck with your new ES Sport.
My car is also an ES Sport So all my entries under the CJ/CF column would be relevant to you with maybe a few exceptions, as
mine is a 2015 model. Most things the same except from mainly minor updates but mostly irrelevant to modding with one definite difference,
Muffler on yours, I'm pritty sure runs across the rear. From 2012 onwards this changed to, front to rear. Will help where I can.
