Exhaust gaskets are vital components within a vehicle's exhaust system, sealing the connection between the engine exhaust manifold and the exhaust pipe. They are designed to withstand high temperatures and vibrations, but over time they can deteriorate and crack. A worn exhaust gasket can cause leaks that can negatively impact engine performance, fuel efficiency, and create unwanted noise. Choosing the right replacement gasket is important, with factors such as material composition and thickness being crucial for optimal performance and longevity.
