I was curious to see if anyone out there is using one of the 30" resonators and what exhaust system you are running. I was looking to put a 5" system on because I like the deep sound but I don't want a drone. Any advice would be appreciated. Looking to pull the plug soon on a turbo back. Also on the 06, do you need a programmer if the kitty doesn't find its way home? Truck is an 06 Mega 4x4 2500. It is bone stock right now but changing. Has 126k miles on it. Had gauges (Turbo, Trans, EGT) since I bought it at 18k miles with a DD trans pan and royal purple. I am buying a Smarty Jr. Controller, regearing to 4.10 and putting in a Trutrack. Was going to upgrade the TC and valve body and put a different turbo and intercooler on it along with larger injectors.
