Lotus Elise / Exige Exhaust Manifold Nut


As the stock Toyota nuts are very shallow and easily rust making them hard to remove and easily rounded, we suggest when changing the exhaust manifold to replace all exhaust manifold nuts.

We suggest using copper-plated high-temperature and corrosion-resistant nuts. The slightly deformed top will prevent the nut from coming to lose similar to how a K-nut works.
