The Volvo exhaust assembly has two jobs that it performs each and every time a car runs. One, it rids the car of dangerous gases and two, it reduces engine noise. As a safety device that carries the carbon monoxide as well as other harmful engine gases well beyond the point that it may come in contact with those in the passenger cabin, the Volvo exhaust system does the best it could. A Volvo Exhaust system that relies on the talents of that work must ensure that the Volvo parts in question demonstrate no frailties, else these parts end up rejected.
The principal components of an exhaust system include exhaust manifolds, the exhaust pipes, the muffler and resonator, the catalytic converter, the tail pipe and a smattering of brackets along with clamps. Inline engines generally have one manifold and a single system of pipes an mufflers leading to the rear of the vehicle. V-type engines have two manifolds instead of one and may have a single or dual set of pipes and mufflers. The exhaust manifold, bolted over the exhaust ports of the engine cylinder head, directs the exhaust gases into the exhaust pipe. The exhaust pipe connects the exhaust manifold and the muffler. V-type engines with single exhaust have crossover pipes connecting one manifold to the other, which then blends into a single pipe.
Mufflers are designed to deaden noise as gases pass through them. An exhaust system may have one or more mufflers. In addition, resonators may be used to further dampen exhaust noises. Mufflers and resonators are connected by intermediate exhaust pipes. With many cars having catalytic converters installed as emission control devices in the exhaust system. Catalytic converters are installed ahead of the mufflers and are generally located under the passenger compartment floor; on some engines, they may be attached directly to the exhaust manifold.
