The exhaust and emissions system muffles engine noise while reducing harmful fuel vapors and exhaust pollutants.

Exhaust gases are collected from the cylinder head by the exhaust manifold which diverts gases from each cylinder into a single pipe. Exhaust gases travel through a catalytic converter where harmful components such as Carbon Monoxide and Oxides of Nitrogen are converted to inert gases. The gases then pass through a muffler, which decreases the noise of the exhaust before exiting through the tailpipe.

The tailpipe is normally located at the rear of the vehicle where exhaust gases have little or no chance of entering the passenger compartment. 

The exhaust manifold gasket is subject to extreme heat as superheated exhaust gases leave the combustion chamber.

A leak anywhere in the exhaust system can pose a threat to the passengers of the vehicle, and to the environment. 

Replacement exhaust parts are made out of various grades of metal and have different life expectancies. Original Equipment stainless steel parts offer far superior corrosion resistance than the common aftermarket grade aluminized low carbon steel versions.

A leak anywhere in the exhaust system can pose a threat to the passengers of the vehicle, and to the environment.

The exhaust manifold gasket is subject to extreme heat as superheated exhaust gases leave the combustion chamber. A gasket placed between the cylinder head and the exhaust manifold keeps exhaust gases from leaking out into the engine compartment. Exhaust manifold gaskets are composed of heat resistant materials. This gasket can leak as a result of degradation or as a result of broken or loose bolts on the exhaust manifold. The exhaust manifold is exposed to extreme heat and rapid temperature changes, and as a result can crack. 

When the gasket leaks or when the exhaust manifold is cracked, exhaust gases enter the engine compartment instead of 

With today's computerized engine systems, maintaining your vehicle's exhaust and emissions system is best left to a professional technician. Have the positive crankcase ventilation (PCV) valve inspected at the appropriate intervals according to your owner's manual. If the system is not operating properly, your vehicle may be hard to start, run rough, be excessively noisy and emit harmful contaminants that will enter the environment.
