Exhaust Systems

A typical exhaust system consists of an exhaust manifold, catalytic converter, resonator, muffler and tail pipe all connected serially to a combustion car engine to flush out exhausts gasses. The exhaust valve allows entry of the hot exhaust gasses into the manifold. The main function of the catalytic converter is to completely neutralize partially combusted gasses such as CO and nitrous oxides that are toxic and harmful to the environment. The cat converter consists of ceramic and platinum or palladium layers. The gasses then move into the hollow muffler chambers of various sizes to eliminate most of the noise they carry from the engine. Resonance and changing directions between the chambers cancels out most of the noise.

Fel-Pro is known for its gasket sets. Typically, catalytic converters, mufflers and pipes require replacements more frequently due to damage or wear and tear with regular driving.

A typical car exhaust consists of a series of parts connected from the engine – prop shaft, exhaust pipe, resonator box, leading into a silencer and tail pipe. The purpose of the exhaust is to flush out the hot burnt gasses generated during combustion of gasoline or diesel in a vehicle engine. The hot exhaust gasses, vapors and the location of these parts lead to significant wear and tear of exhaust parts. Any damage, cracks or holes in the exhaust tubing leads to significant noise. Leaks, breaks and rattles often appear at the manifold joint or rubber mountings, often due to excessive engine movement or bar bushes. Exhaust metal-to-metal tubing joints are often joined together using clamps, nuts and bolts, that require careful positioning. Fitting new clamps or mountings to an exhaust pipe may require cutting through pipes with a mini hacksaw. The pipes are usually held in place under a car body with specific mounts and screws. Having a faulty catalytic converter can lead to a failed emissions test.
