If you want to dramatically increase braking performance without added wear to your vehicle brakes. An exhaust brake is something to seriously consider. These are almost a neccessity if you frequently tow a moderate to heavy trailer or RV. I plan to install one of these on my 2002 Dodge 2500. The Jacobs and Cummins E-Brake are the ONLY exhaust brakes that are compatible with the engine and vehicle warranty.

My wood cutting partner has one on his 1999 Dodge Ram 3500 and it works great, not to mention it sounds cool when you activate it too! :thumbsup:

He tows a goose neck trailer with his Gehl 6635 and other stuff on it and the exhaust brake REALLY helps out!

You may want to make sure you can use them in town. Some places don't allow the use of Jake brakes due to the noise. :eek:

These are not the Jac Brakes you are thinking of Stewart. You are thinking of the Jacobs Engine compression brake which is a totally different animal. As long as you have reasonable exhaust system on the truck; they are not very loud. Through a straight piped exhaust; they are tremendously loud.

Here is a little info. on the Jacobs Engine Brake:

Jody, the big rigs mostly use an engine compression brake. The Cummins engine in the Dodge pickup uses an exhaust brake. Two different things. an exhaust brake is basicly a valve that restricts exhaust flow against the engine. It is mounted usually on the exhaust turbine of the turbo charger. The engine compression brake is mount in the cylinder head. An uses engine compression to brake the vehicle.

Unless you have an N-14 and up under the hood sheet metal in your pickup or vehicle you drive; ya ain't gotta Jake Brake. Sorry guys. The Jacobs exhaust brake would not make pimple on the butt of a Jake Brake as far as sound goes.
