The tune for sure! As far as exhaust your going to get a large number of guys telling you not to do it. I will tell you that you won’t see any power difference with an aftermarket exhaust setup but the type of sound you will get will vary greatly from one company to another. I went through three different exhaust setups in a span of 4 weeks. The first setup was the 4” AFE Mach Force xp. It is a well made system and looks great but I knew immediately that the sound was not for me. The amount of cabin noise was WAY more than I was looking for and the sound at low RPM was not very good. I had the AFE exhaust removed and had a custom setup put on with a Flowmaster Super 10 mufler the very next weekend and it was much the same although the exterior sound of the flowmaster was much nicer sounding at low rpm. The following Monday I ordered the Borla Touring 3” system per the recommendation of the guys at American Trucks. They told me that the Touring setup is the closest sounding exhaust to the factory setup on the Raptor so I purchased it. $1200 shipped and it was worth every penny IMO. Very quite in the cab an very nice sounding when you give it some throttle. At first I thought it was too quite due to the lack of volume in the cab but I had my wife drive it a little aggressively while I was outside listening and it sounds great! I am very happy with the purchase and I get several compliments from people about the sound.
