2-Bolt Flange Hardware — Service Replacement

GReddy exhaust systems use 2-bolt flange connections at mid-pipe section joints. The hardware at these connections — typically spring-loaded bolts, springs, and nuts — is exposed to repeated heat cycling, road salt, and exhaust gas condensation, causing corrosion and eventual hardware failure. Worn or broken flange hardware allows the joint to separate and causes exhaust leaks at the flange connection. The 11000300 kit provides OEM-spec replacement hardware to restore a properly sealed and mechanically sound flange connection on any GReddy exhaust system using the standard 2-bolt flange design.

Spring-Loaded Flange Design

GReddy’s 2-bolt exhaust flange connections use spring-loaded bolt assemblies rather than solid clamp hardware. The springs allow controlled movement at the flange joint as the exhaust system expands and contracts through heat cycles — this prevents stress cracking at the flange faces that would occur if the joint were rigidly clamped. When the spring hardware wears or breaks, the joint loses its controlled compliance and begins to leak. Replacing the spring hardware restores the designed flange behaviour and sealing.

Universal GReddy Fitment

Fits GReddy exhaust systems using the standard 2-bolt flange configuration across their JDM and performance application catalog. If you are unsure whether your GReddy exhaust uses the 2-bolt flange hardware this kit replaces, compare your existing flange bolt hardware against GReddy’s parts diagram for your specific exhaust system before ordering.

Inspect flange face condition and gasket (if applicable) before installing new hardware — damaged flange faces will continue to leak regardless of new hardware. Torque to GReddy’s specification. Anti-seize on bolt threads recommended to prevent future corrosion bonding.
