Exhaust boxAn exhaust box is attached to the exhaust pipe is usually tubing used to guide waste exhaust gases away from a controlled combustion inside an engine or stove. With an internal combustion engine it is usually part of an exhaust system. Which conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, the exhaust gas may flow through one or more of:-
A turbocharger to increase engine power. A catalytic converter to reduce air pollution. A muffler (USA) / silencer (UK), to reduce noise.
An exhaust pipe must be carefully designed to carry toxic and/or noxious gases away from the users of the machine. Indoor generators and furnaces can quickly fill an enclosed space with carbon monoxide or other poisonous exhaust gases if they are not properly vented to the outdoors. Also, the gases from most types of machine are very hot; the pipe must be heat-resistant, and it must not pass through or near anything which can burn or can be damaged by heat. A chimney serves as an exhaust pipe in a stationary structure.
During the exhaust stroke, a good way for an engine to lose power is through back pressure. The exhaust valve opens at the beginning of the exhaust stroke, and then the piston pushes the exhaust gases out of the cylinder. If there is any amount of resistance that the piston has to push against to force the exhaust gases out, power is wasted.
Using two exhaust valves rather than one improves the flow by making the hole that the exhaust gases travel through larger. In a normal engine, once the exhaust gases exit the cylinder they end up in the exhaust manifold. In a four-cylinder or eight-cylinder engine, there are four cylinders using the same manifold.
From the manifold, the exhaust gases flow into one pipe toward the catalytic converter and the muffler. It turns out that the manifold can be an important source of back pressure because exhaust gases from one cylinder build up pressure in the manifold that affects the next cylinder that uses the manifold.

Exhaust SilencerExhaust silencer information
The Exhaust Silencer and muffler absorb and attenuate noise levels from machinery and other sources for environmental regulatory compliance. They use several basic designs. Absorptive silencers and mufflers incorporate sound-deadening materials, fabric and compounds to absorb the noise energy from the flow of gas or air. Reactive silencers and mufflers use complex passages and/or chambers to optimize noise reduction while maintaining application requirements such as pressure drop, airflow and size. Hybrid designs use both absorptive and reactive design elements, combining airflow path management and acoustical materials to reduce noise. By contrast, active noise cancellation devices use sound sensors to characterize the sound profile and noise-canceling speakers to produce sound 180° out of phase with the airflow noise.
Exhaust silencers mount on the outlet or exhaust of the muffled device. In terms of placement, both inlets and outlets can be located either in-line or on the side. Special features for industrial silencers and mufflers include a filter silencer, separator silencers, and spark arrestors. A Filter silencer consist of filters, traps, or screens for removing dust, grit, water or other impurities from the flow of gas or air. A Separator silencer include components that physically separate water from the flow. Spark arrestors are designed to trap hot carbon and soot particles. They usually feature a chamber design and are used in combustion exhaust applications to minimize danger and maintain air quality.

What is an exhaust manifold? What is an exhaust manifold?
Made of cast iron or tubular steel, the exhaust manifold mounts to the exhaust side of the cylinder head. An exhaust manifold gasket is used at the connection to ensure a good seal. Engines with their cylinders arranged in-line usually have one exhaust manifold. Engines with V-type cylinder arrangements, like the V6 and V8, have two separate exhaust manifolds, one mounted to each cylinder head.
What is the purpose of an exhaust manifold?
The exhaust manifold routes the exhaust gases leaving the cylinder head to the exhaust system. As such, the manifold also serves as a connection point for the exhaust pipe. Depending on engine configuration and the number of exhaust manifolds, there may be two exhaust pipe connections.
Depending on the year, make and emissions equipment installed on the vehicle, the exhaust manifold may also serve as a mounting location for hardware of the air injection system or for an oxygen sensor. Also, some exhaust manifolds may still include a heat riser valve, controlled by a temperature-sensitive spring. This valve is designed to help divert hot exhaust gas through a separate passage in the intake manifold to aid in better warm-up driveability.
Maintenance tips
Although not commonly replaced with other exhaust system parts, exhaust manifolds should be checked periodically to ensure they are tight, free from cracks, and that the exhaust pipe mounts are secure. A ticking noise during acceleration or the sound or smell of leaking exhaust could indicate a leak at the manifold or its connections.
However, don't rely on your sense of smell as a conclusive means of determining if threes an exhaust leak. Carbon monoxide has no odor. If you suspect any problem with the exhaust system, have it inspected immediately by a professional technician. Another symptom of a potential exhaust leak is a failed emissions test. A leak not only lets exhaust gas out, it also allows oxygen to enter the exhaust stream, which can be detected during an emissions test. You will usually be required to make repairs before retesting, so have the leak checked by a professional technician.

Exhaust pipe information Exhaust pipe information
Exhaust pipe is a general term for several different pipes used throughout the exhaust system. Although configurations vary with different makes, models and engines, there is usually a front exhaust pipe connecting the exhaust manifold to the catalytic converter, an intermediate exhaust pipe connecting the catalytic converter to the muffler, and a tailpipe connected to the outlet of the muffler and serving as the exhaust outlet.
Exhaust pipes may be made of standard or stainless steel. Exhaust pipes route exhaust gas away from the engine, through the catalytic converter and muffler and out the rear of the vehicle. As a result, pollution and sound are reduced, while ensuring safety by directing exhaust gas away from the vehicle.
Exhaust pipe tips.
Have your vehicle's exhaust system inspected periodically to keep your car safe. Exhaust pipes may not be individually replaceable due to the condition of other exhaust system components, or because the original exhaust system uses a unitized construction, where sections are welded together. Keep in mind that exhaust gas, especially carbon monoxide, can be deadly if it enters the interior of the car.
The symptoms of an exhaust leak may include a louder than normal exhaust sound, the sound of exhaust coming from unusual places on your car, a ticking noise when accelerating, and the smell of exhaust. However, don't rely on your sense of smell as a conclusive means of determining if there's an exhaust leak. Carbon monoxide has no odor.
