Discharge Flange Gasket for GT series 2.5in

The Vibrant Performance Discharge Flange Gasket for GT series 2.5-inch outlet is a precision turbo component engineered for reliable boost system sealing on T3 GT-series turbos with 4-bolt discharge flanges. This stainless steel gasket maintains critical pressure integrity at the discharge junction, where turbine outlet flow transitions to the exhaust manifold or downpipe—a junction that experiences extreme thermal cycling and pressure variance during sustained boost.

Manufactured from stainless steel, this gasket resists corrosion and thermal degradation in the hostile discharge environment where exhaust gas temperatures routinely exceed 1,000°F. The 2.5-inch outlet specification matches OEM GT-series turbo discharge ports, ensuring proper flow characteristics and sealing surface contact pressure. At 0.03 lbs, the gasket introduces negligible weight while delivering the structural integrity required to prevent boost leakage—even critical point in forced-induction calibration and spool consistency.

This component addresses a core durability concern in high-boost applications: discharge gasket degradation leads to compressor surge, uncontrolled boost spikes, and tuning instability. Operators and technicians building or maintaining GT-series turbo systems—whether for motorsport, street performance, or boost-dependent power applications—depend on OEM-specification gasket replacement to restore factory sealing geometry and prevent recurrence of boost-related issues. The T3 GT flange standard ensures compatibility across the full GT-series lineup.

Stainless construction and precision tolerancing make this gasket suitable for repeated thermal cycling and pressure cycling over thousands of boost events. Whether restoring a failed turbo installation or executing preventive maintenance on a high-mileage forced-induction engine, this Vibrant Performance OEM-grade gasket delivers the reliability required for consistent turbo performance.
