4.00 Inch 3 Bolt Exhaust Gasket

The 4.00 Inch 3 Bolt Exhaust Gasket by QUICK TIME PERFORMANCE is a precision-engineered sealing component designed for automotive enthusiasts and professional mechanics working with high-performance exhaust systems. This gasket serves as the critical barrier between your exhaust manifold and header collector, preventing exhaust gas leaks that rob engine efficiency and create unwanted noise.

Built to withstand extreme thermal cycling and exhaust gas temperatures, the Quick Time Performance 4.00 inch gasket features a three-bolt mounting pattern that aligns precisely with standard manifold and collector flanges. The gasket's thickness of 0.25 inches ensures proper fitment without requiring extensive modification to surrounding engine bay components. High-temperature composite construction resists gasket blow-out and thermal degradation, maintaining a reliable seal across the RPM band.

This exhaust gasket benefits anyone upgrading from factory restrictive manifolds to aftermarket headers or building a custom exhaust system from the ground up. Installation is straightforward during header installation or manifold work—align the three bolt holes and torque to specifications for a secure fit.
