One thing to consider, if you have a manual transmission, the exhaust brake is a good investment and you won't regret it. If you have the automatic, you should not install one if you have not had the transmission rebuilt and upgraded for the use of an exhaust brake. The 48RE, in its stock form, will not handle the reverse torque from the use of the exhaust brake. That is why it was never offered from the factory as an option for the automatic.
Incorrect. The 06 was the first year of the factory option Jacob exhaust brake. The trucks came ready to install with all electronics ready to go. The part is about $1200 from a mopar dealer and a 4 hour labor charge. No need to upgrade anything other than to upgrade for your own piece of mind.
