The LiteFlex Coupling 3in In/Outlet 4in Long from Vibrant Performance is a precision vibration isolation component designed for high-performance automotive exhaust and intake systems. This coupling bridges misaligned or offset connections between exhaust components, turbo discharge pipes, intake manifolds, and silencers without introducing rigid stress points that amplify vibration throughout the powertrain.
Built for enthusiasts and professional tuners who demand clean power delivery and reduced resonance noise, this flex coupling eliminates the need for expensive custom fabrication or loose-fitting connections that compromise system integrity. Engineered with Vibrant's proprietary LiteFlex material, this 4-inch-long coupling features a 3-inch inlet and outlet diameter, offering lightweight yet durable flex properties that absorb thermal expansion and mechanical movement without metal fatigue.
The flexible inner core allows ±10-degree angular misalignment while maintaining airtight seals, critical for turbo systems where even minor leaks degrade boost response and fuel economy. At just 1.21 pounds, this component adds negligible weight to your system while the compact 4.33-inch cube dimensions fit tight engine bays typical of modern performance builds—from LS-swapped platforms to late-model turbocharged four-cylinders.
