Just picked up a 2007 3500 lbz crew cab dually . 90k bone stock one owner . Just want some advice on upgrades I should do and what stuff I should stay away from . It's a daily not looking for balls to the wall power because I have a 1200hp Camaro to do that Just want something reliable and sounds nasty. Just order a MBRP 4in turbo back plm serious exhaust and a S&B intake with lower scoop . What other parts would be a good buy ? Thanks
