I just purchased a 2007 2500 automatic with the 6.7, my first diesel. I know very little about all of the emmsions crap they put on the truck. I lifted the truck 6" and run 37x12.5R18s. I am getting around 11 mpg. I would really like to be able to hear the motor over the tires. Can anyone advise me on what would be the best plan of attack. I don't know much about all the available options. I am thinking starting with an intake, dpf delete pipe, and a programmer. I am not sure which types and where would be best to get these from. Any help would be greatly appreciated. Thanks
