An exhaust gasket is a critical part of your factory exhaust system. There are many types, but their role is simple. An exhaust gasket is used to seal connection points throughout your exhaust system, preventing leaks and ensuring that all exhaust gases pass through the catalytic converter for proper handling and treatment.

Types of Exhaust Gaskets

There are three main types. An exhaust manifold gasket seals your exhaust manifold to the cylinder head in the engine. V6 and V8 engines feature two exhaust manifolds, requiring two exhaust manifold gaskets. This is the gasket that ensure that the noxious exhaust fumes flow into the catalytic converter, as required by law.

The other two types are flange and ring gaskets. They seal other connection points throughout the entire exhaust system, such as the connection between the exhaust pipe and exhaust manifold.

Exhaust gaskets are typically made of embossed steel, fibrous materials, graphite, or even ceramic composite. Some may even combine multiple materials. The key? The gasket needs to be formed of a high temperature material in order to withstand the heat produced when your engine is running.

How to Spot Failing Exhaust Gaskets

Over time, exhaust gaskets can wear out. That's not good, since harmful gases can escape into the atmosphere -- or foul the air that you're breathing inside your cabin. Signs of trouble include:

Excessive exhaust noise

Reduced engine power

Trouble accelerating

Worsening fuel efficiency

You detect the odor of fuel in the air
