I have a 2010 SXT with the 3.5: engine in it. The so called duel exhaust available thur Chrysler is a single pipe opened into two outlets. I don't like it. The 5.7 hemi ehaust system available thur Borla Flowmaster Gibson and other will fit if you know a simple trick that your muffler shop guy can do for you. I choose the Gibson kit. It uses the factory hangers and there is not any wrinkle bends in it. It sounds good, 50 State leagal and provides a real punch from idle up. About a 25 HP gain and I do not know what amount of torque is gained. I have this system on my car now. Looks great sounds great and emproves the fuel milage in town a bunch. Let me know if I can help you in any way. I will be travling to Dallas 12/11/10 and I will report the milage on this 2010 with the new duel exhaust system on it when I return on the 13th.
