EXB-4154 Exhaust Brake 55 Pound Back Pressure; 4 Inch Diameter

Avoid the feeling of panic in hard or prolonged braking situations with diesel engine vehicles. Gas engines are designed with a throttle or butterfly valve that closes the air intake of the engine forming a vacuum effect that assists the vehicle in braking. Diesel engines have no such butterfly valve and thus no compression is developed when the throttle is released during braking. This means the brakes are given the entire task of getting the vehicle stopped. The D-Celerator® works like this - an oversize nodular iron housing consisting of two stainless steel butterflies (one large, one small) is added to the exhaust system in front of the muffler.
