Automotive exhaust systems consist of various parts designed to duty cool.
Automotive exhaust systems muffle exhaust clang and chop exhaust emissions. While materials and configuration differ among several cars and trucks, all exhaust systems can be broken down into three popular sections: the exhaust manifold/headers, the mid-pipe and the muffler/tailpipe.
Exhaust Manifold/Headers
Looking to the front of the engine, the inaugural quota of an exhaust is referred to either as an exhaust manifold or a header. Generally, a header Testament enjoy alone runners for Everyone exhaust cylinder, whereas an exhaust manifold is one substantial abbreviate, which contains a collector into which all the exhaust gases dump.
Muffler/Tail-pipe
The tailpipe will meet the mid-pipe near the rear of the vehicle and directs the exhaust gases out to the atmosphere. Some smaller vehicles may have the muffler integrated into the tailpipe section, as the muffler can only go where there is sufficient space.The mid-pipe Testament be the Centre quantity of an exhaust, starting under and persist the engine, where it meets the exhaust manifold/header. This quota normally contains the mufflers of an exhaust manner. In V8 applications, this quota may be an H or X drainpipe, where the two sides are connected to facilitate equalize gases in a dual exhaust. While a V8 has apart a unmarried exhaust, a crossover pipe will run from one side to meet up with the single mid-pipe. Catalytic converters are typically mounted at this point, between the exhaust manifold and the mid-pipe.
When a company refers to a "cat-back" exhaust system, it usually means a system which starts at the mid-pipe, and thus starts behind the catalytic converter.
Some systems may have resonators, devices designed to help muffle the exhaust gas notes, in this portion of the system.
Many manufacturers first off carry a catalytic converter into this quantity to maintenance intersect cold-start emissions. Message that V8, V10 and V12 engines accept two banks and thus a manifold on Everyone side of the engine.
