Exhaust Gaskets
Exhaust gaskets create the leak-free seal between your exhaust manifold, headers, downpipe, and catalytic converter. Quality gaskets are critical for preventing exhaust leaks that reduce power, increase emissions, and create safety hazards in the engine bay. Popular Upgrades Most frequently replaced exhaust gaskets include exhaust manifold-to-head gaskets for high-mileage vehicles, turbo downpipe gaskets for boosted engines, and collector gaskets for custom header builds. MLS (multi-layer steel) gaskets are the most popular choice for performance applications. What types of exhaust gaskets are available? Exhaust gaskets come in several types: multi-layer steel (MLS) gaskets for high-performance and boosted engines, copper exhaust gaskets for custom and race builds, graphite gaskets for OEM-style replacement, and specialized turbo inlet and outlet gaskets for turbocharged applications. Can I reuse exhaust gaskets? Most exhaust gaskets should not be reused, particularly MLS and graphi...
