Exhaust or jake brake or neither?

An 'engine brake' is on the engine and controls exhaust valves opening them.....when engaged you will hear a loud pop-pop-pop sound (just like the semis)

IMO this is a bit misleading because most MH's have a muffler on their engine brakes, (aka Jake Brakes) and are pretty quiet. Any pop pop noise is hardly discernable.

Jacobs Company also makes an exhaust brake so both are sometimes called Jake Brakes. If you have an exhaust brake - just call it a Pac brake and no one will be confused.
