I do not plan to Mod it any more than I have with any other car I have had. Usually if I like the car and plan to keep it a few years I will put in a K &N filter. I am more intrested in keeping it running good so that I can drive and enjoy a vehicle everyday with out alot of constant fuss.
I know PA has a visual inspection for gas powered as well as the computer hook up emissions test. I would think diesel would require the visual too so I dont think I can take off the muffler.
K&N filter = bad idea on these Jeeps. You can go with it if you want, but most folks on here won't recommend it. Get an Amsoil Ea filter instead. Costs only $30, good for 100k miles, and you vacuum it clean. It still lets in much more air than stock, but it won't let in the large particles that a K&N will.
The muffler mod is relatively cheap (parts & labor ~$100, or, if you are a do-it-yourselfer, $70 for the Magnaflow). It will improve mileage slightly by significantly improving your Jeep's ability to coast downhill and up to stop lights.
GDE is a little more expensive, but you will make the money back after a year or two of driving (depending on your commute). More importantly, GDE improves drivability (smoother shifting, better coasting, no black smoke), longevity (by virtually eliminating the EGR) and all around fun (ask anyone who has one, I get mine next week!).
Of course, I consider myself the type of person who drives a vehicle into the ground before I will buy another one. So I'm looking to make my Jeep last as long as possible and get the best mileage possible. I only really plan on doing the above mods, but they will pay for themselves in a couple of years and significantly improve my Jeep's lifespan and my driving experience
