Eliminate annoying exhaust leaks and restore back-pressure with the NCY Performance Exhaust Gasket. Engineered for the high-vibration environment of GY6 engines, this gasket features a specialized metal-and-fiber composite construction. Unlike soft paper gaskets that blow out under heat, this hybrid design provides a crush-resistant seal that conforms to surface irregularities between your exhaust manifold and the cylinder head, ensuring your engine runs quiet and efficiently.
Key Performance Features
- Steel & Fiber Composite: Combines the structural integrity of steel with the sealing flexibility of high-temp fiber for a long-lasting, leak-proof interface.
- High-Heat Resistance: Specifically formulated to withstand the extreme temperatures at the exhaust port without degrading or becoming brittle.
- Universal GY6 Fitment: Designed with a slotted bolt-to-bolt pattern (45mm–51mm) to accommodate various head and manifold tolerances.
- Optimized Port Flow: The 27mm internal diameter is matched to standard GY6 performance manifolds to minimize turbulence at the exhaust exit.

Mechanic's Note: An exhaust leak at the head can cause popping on deceleration and even lead to burnt valves over time.
Installation Tip: Always clean the cylinder head mating surface with a scraper or wire brush before installing the new gasket.
Pro Tip: Re-torque your exhaust nuts after the first 50 miles of riding; the gasket will "settle" after its first heat cycle and may require a final snugging to maintain a permanent seal!
