A typical exhaust system consists of an exhaust manifold, catalytic converter, resonator, muffler and tail pipe all serially connected to a combustion car engine to flush out exhaust gases. The exhaust valve allows the entry into the manifold of the hot exhaust gasses. The catalytic converter's main function is to completely neutralize partially combusted gasses such as CO and nitrous oxides that are toxic and environmentally harmful. The cat converter is made of layers of ceramic and platinum or palladium. The gasses then travel through different sizes of the hollow muffler chambers to remove most of the noise from the engine they bring. The vibration between the chambers and changing directions cancels most of the noise.

Fel-Pro's gasket sets are well known. Catalytic converters, mufflers and pipes typically require replacements with regular driving more frequently due to damage or wear and tear.

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.
