Your performance truck weighs a lot. That means when it is rolling, it builds up a lot of momentum. To bring that much momentum to a standstill requires a lot of work. Sure, your disc brakes are designed for such a task, but braking puts an awful strain on them. Banks Exhaust Brakes may be an affordable way to prolong the life of your disc brakes and make braking in general an easier process for your truck. Basically, a Banks Exhaust Brake forces your engine to work backward. The exhaust brake cuts off the line between your engine and your exhaust, so gases build up in the manifold and are then compressed. This, in effect, is the opposite of what your engine is trying to do - burn fuel and send that gas out - so the engine is forced to compensate. When it does, it stops sending out that power to your wheels, and your truck begins to slow. Exhaust brakes, however, are not the most effective means of stopping, and downshifting often achieves the same results. That said, Banks Exhaust Brakes are far less noisy than engine brakes, and the may present a viable braking solution to anyone who drives a lot within a city.
