These are the Grimmspeed Head to Exhaust Manifold Dual Port Gaskets. These particular gaskets see some of the highest temperatures than any other gasket on the engine. With that being said anytime you remove your exhaust manifold for maintenance or for upgrades, make sure that your exhaust gaskets are in good shape to avoid exhaust leaks which can create more labor for you or your mechanic. Although the factory gaskets are made of metal materials, they can come apart upon removal.
Grimmspeed relieves this issue with a set of Exhaust Manifold Gaskets crafted from quality metal materials to promote a good exhaust manifold seal. These are sold as a pair and will come ready for the installation.
