first off, you got a 3.6L engine, already at over 305 HP at the crank. headers are a no go on these engines as the exhaust manifold is made into the head. but you can still put on a good cat back exhaust system. plenty out there for your choosin. https://www.diablosport.com/predator-2-tuner-for-ford-gmc-chevrolet-dodge-ram-chrysler/#intro like above is for a tuner for your car. they do a great job in getting the max out of that engine.
Contact Wil (Link below) over at Overkill about getting a Tuner n a Tune from him. Great to work with and his Tune make a BIG difference over the Canned Tune from DS. Hunt around for prices, but it the long run it's usually cheaper to buy the Tuner (Handheld) and get a free tune from Wil then it is to buy a tuner and then pay him for a Custom Tune. PLUS after u get a Custom Tune you'll get Free re-Tunes, as in, changing ur exhaust or adding a TB, ect. His Tunes ROCK, the engine is running a lot smoother AND it is much quicker!!! Mine is a '13 SXT. Caveat: some 2015 engines need a whole new PCM. He'll know so contact him. I added a CAI and I thought it made a difference, although others say it doesn't, BUT it sounds AWESOME! Even if it never made a difference in performance I would spend the money just for the sound. Again, be patient n hunt around to find good deals.

Before you take it back to a Dealer for service you return it back to Stock. You obviously have to decide for yourself, but my understanding is no matter what you do to the vehicle the dealer isn't going to like it, but its also my understanding they have to prove what you did/changed was the direct cause of any issue. There's arguments on both sides of that coin so you need to do due diligence in researching that. I will say that DiabloSport tuners, at least the iTune2 that I use, is painfully SLOW! If I'm going out to return it to stock, or from stock to install a tune, I'm looking at 35+ minutes! If everything goes right. But the results are worth it. The tune, either DS or Overkill, definitely adds noticeable low-end torque. It's still NOT a V8, but it ain't far from it. AND I'm still getting 30-31 mpg highway at 75. So I'm a Happy Camper.
If you don't mind, take a few pictures of the mud guards. Like dn the side, from the back, ect. I've been thinking of getting them, but just not sure I would like the way they would look. Thanks ...
unless you got a mod friendly service manager and a good mechanic that dont mind that. Glad I got the one I have.
That's true, you're lucky. The BIGGEST concern is having the Dealership/Repair Shop re-flash the PCM, then you're locked out of ur Handheld Tuner! But you can get a OBD port cover that states DO NOT REFLASH. I believe you can get DS to unlock the Handheld, but there's a lot of Hoops to jump through. Again, I'm REAL happy with the Tune I got from Overkill! It runs so much smoother, the TQ locks up a little tighter and it's faster! What more can ya ask for ...
