SCE Gaskets Pro-Copper Exhaust Gskt - GM LS1 4019

Header and exhaust manifold gaskets experience extreme thermal cycling and pressure cycles—failure here leads to exhaust leaks, performance loss, and potential engine damage. SCE's Pro-Copper gaskets are engineered to handle the demands of LS-series engines with superior sealing integrity and heat resistance that stock gaskets simply cannot match. A quality gasket swap is one of the most cost-effective reliability upgrades you can make, especially if you're running forced induction or sustained high RPMs.
