Tranny or clutch upgrade is a must with added power, Smarty is the way to go on a tuner for Dodge, i love mine. Exhaust is gonna depend on your emission laws where you live, if you want to do a big tuner like smarty, removing the cat is a must, again check your local laws first, and you can go with a 4 inch turbo back exhaust, if laws are aganst it and your a good (law abiding citizen)you can get a cat back system but dont go with a big tuner or run one on the higher settings unless you wanna lose a turbo or something else expensive, do some asking around before you buy exhaust, I Build my own exhausts and intakes so i am not too familiar with the aftermarket products. On the intake my 2 favorites are banks and AFE. Thats the 2 i have had the best feedback out of. Also with any added power install a pyro and boost guage so you can see whats goin on
