NCY 125-232cc GY6 27mm Exhaust Gasket - 27x2.2mm

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.

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!
