Anyone heard of an exhaust brake for these engines?

Won't work well on ours as you also need to integrate TCC lockup control so torque converter does not unlock and engine can slow the vehicle,

Mine is a manual so I dont have a torque converter... Im seriously wondering if it can be done though? I know our engines have alot of slowdown potiential by there selves because of the giant compression ratio these engines have

Yours then is a better candidate/possibility, guys at Heath one time sold a engine brake don't know if they still do, at any rate they could give you some ideas of what is possible solution for the 6.5

Here is a couple of places that advertise 6.5 diesel exhaust brakes. I have thought about getting one too but that is way down on my list.
