It's recommended to upgrade your exhaust valve springs to 60lbs or more if you install one and I've heard both ways on wether or not its good or bad on the engine. I've rode in a 07 2500 cummins with a utility bed loaded down to the max with a welder, compressor and other such equipment and it made a big difference when it was on and off; saves the brakes too. Only down side that I've heard is a mechanic at the dealer told us that if you don't run with it on alot it will stick up with carbon and jam sometimes open sometimes closed

Here's another comment in favor of the exhaust brake.... Aside from "it works", and "saves the wheel-brakes", somebody a long time ago, in a webthread far, far away said that its use would keep the exhaust valves from cooling too rapidly and warping on the downhill side after a high-temperature climb. I have no idea if that's a real concern, but, it sounded plausible to me.
