2012 Toyota Venza - Exhaust Manifold Outlet Flange Gasket

What is an Exhaust Manifold Flange Gasket?

An exhaust manifold flange gasket or collector gasket is a sealing component used in the exhaust system, specifically at the connection point between the exhaust manifold outlet and front exhaust pipe. The purpose of the exhaust manifold flange gasket is to create a tight seal between the front exhaust pipe and exhaust manifold outlet and prevent exhaust leaks. The collector gasket is usually made of metal or a hard fibrous material to stand up to the heat and pressure of the exhaust system, and fits between the two flanges of the connecting pipes. Over time, the exhaust manifold flange gasket can degrade or be damaged by high heat, engine vibrations, or exposure to corrosive elements. When this happens, the gasket may fail to create a proper seal, leading to exhaust leaks. These leaks can result in decreased engine performance, increased emissions, exhaust noise, and the potential for harmful fumes entering the vehicle's cabin. Inspecting the exhaust system can help you determine the source of the exhaust leak, so be sure to check the manifold flange gasket for signs of damage and replace it if it has failed. If you have an exhaust leak and need a replacement exhaust system component, shop O'Reilly Auto Parts for new exhaust manifold flange gaskets, exhaust manifold gaskets, exhaust hangers, and more for a complete exhaust repair.
