2. Exhaust system - Wikipedia

   en.wikipedia.org/wiki/Exhaust_system

   Cat-back exhaust systems generally use pipes of larger diameters than the stock system. To reduce backpressure, the mufflers included in these kits are often glasspacks . If the system is engineered more for show than functionality, it may be tuned to enhance the lower sounds from high-RPM low- displacement engines.

3. Exhaust brake - Wikipedia

   en.wikipedia.org/wiki/Exhaust_brake

   An exhaust brake is a means of slowing a diesel engine by closing off the exhaust path from the engine, causing the exhaust gases to be compressed in the exhaust manifold, and in the cylinder. Since the exhaust is being compressed, and there is no fuel being applied, the engine slows down the vehicle: the crankshaft (and, hence, the wheels ...

   A 4-2-1 exhaust system is a type of exhaust manifold for an engine with four cylinders per bank, such as an inline-four engine or a V8 engine. The layout of a 4-2-1 system is as follows: four pipes (primary) come off the cylinder head , and merge into two pipes (secondary), which in turn finally link up to form one collector pipe.

   Caterpillar increased the power output of the Cat 3524B EUI 24-cylinder diesel engine used in the 797 from net 2,394 kW (3,211 hp) to net 2,513 kW (3,370 hp) enabling the 797B to achieve a 68 km/h (42 mph) top speed when transporting a 345 t (380 short tons) load, a 3.2 km/h (2 mph) increase over the first generation 797.

7. Exhaust heat management - Wikipedia

   These ceramic coatings are highly advanced coatings applied via plasma spray, and as a result, the coating is effectively welded to the surface of the exhaust system. They can offer small performance benefits [1] due to the low thermal conductivity of the ceramic compound. This reduces engine bay temperature and increases exhaust velocity.
