BMW Exhaust Gaskets Hangers and Parts for BMW E46 M3 S54 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

Exhaust systems are typically split among multiple sections and each section has its own form of fasteners and attachment points. The gaskets, hangers, and seals that join each section together should be replaced any time the exhaust is removed. As the exhaust is tightened together the gaskets and seals are crushed or deformed to form a tight seal. Re-using them is possible but greatly opens up the potential for an exhaust leak. Exhaust leaks can lead to a number of major and minor problems including power loss, check engine faults, and noise issues. Replacing your hangers and gaskets will ensure you don't have to take the exhaust down all over again.

Crafted from high-strength 6031 billet aluminum and finished in a sleek black anodized coating, it delivers both durability and corrosion resistance. With this collar in place, your exhaust stays exactly where it should—no rattles, no surprises.
