Subaru Forester loud exhaust issue after manifold gasket replacement, possible need for gasket sealer on Subaru Forester

Some Subaru Forester owners report experiencing loud exhaust issues after replacing the manifold gasket, which may indicate problems with the installation or sealing of the new gasket. To address this, some owners find that applying a gasket sealer can help ensure a proper seal between the exhaust manifold and the engine's cylinder head, crucial for preventing exhaust leaks and reducing noise levels. Additionally, using a gasket sealer can enhance sealing properties, especially in cases of minor imperfections in the mating surfaces. However, if loud exhaust noises persist even after applying a sealer, it is advisable for owners to seek professional inspection to identify any underlying issues. Proper installation of the exhaust manifold gasket, along with gasket sealer application, is important for maintaining the integrity of the exhaust system and ensuring optimal performance of the Subaru Forester.
