Specifications

Fitment & Compatibility

This HKS exhaust gasket is a genuine replacement part designed specifically for compatible HKS exhaust systems. Fitment is determined by the specific HKS exhaust assembly it was engineered for. To confirm compatibility, cross-reference manufacturer part number G65455-K00440-00 with your HKS exhaust system documentation or contact HKS tech support with your vehicle's year, make, model, and current HKS exhaust part number. This is not a universal gasket — it is an application-specific OEM replacement.

Is this a universal exhaust gasket? No. This is an application-specific HKS OEM replacement gasket. Always verify compatibility with your exact HKS system part number before purchasing.

Installation

Installation is a straightforward bolt-on replacement suitable for experienced DIYers and professional technicians. Allow the exhaust system to cool completely before beginning work. Remove the fasteners at the affected pipe joint, clean mating surfaces of any old gasket material or carbon buildup, seat the new gasket evenly, and reinstall hardware to the manufacturer's specified torque. No cutting, welding, or fabrication is required. For best results, replace exhaust gasket hardware (bolts/nuts/springs) if signs of corrosion or stretching are present.
