You are mistaken, many make headers long and short for the ram. One guy in cal, makes long tube with 3'' mids, another in Ohio is also developing long tubes, DC also makes long tubes , gibson makes shorties, and corsa is also making shorties. No lowering kit is available other than blocking the rear.The only engine upgrades is normal v-10 performance parts. A few companies are making CAI's. With the shorties you are going to be about 10hp down from the long tubes. Most are going to 4.56 with 3'' system out the back with a Vec 2, gaining 40hp or more in some cases with headers. But the vc 2 gives about 60hp on bottom alone, but only about 5 on top.
