Jake vs Exhaust Brake

The exhaust brakes used on pick up trucks are all utilizing back pressure in the exhaust system. They create a little more reverse horsepower than what downshifting alone does. This little bit of added reverse horsepower is enough to make a huge difference on grade braking in an application when you are only holding back about 25000 lbs (combined weight of truck and trailer) on a typical highway grade. So for your application a simple exhaust brake consisting of a programer that controls the vanes on your turbo is all that is required. There is an exhaust brake made for the Ram that holds the exhaust valve off its seat during the compression stroke which is more effective than a standard exhaust brake but it is not the same as an engine decompression brake ... which is what has been traditionally referred to as a "Jake Brake".
