Vibrant SS Flex Coupling with Inner Braid Liner 3in inlet/outlet x 6in long for 02-21 Subaru WRX/STI
Vibrant Performance 63006 delivers stainless steel flex coupling precision for 2002-2021 Subaru WRX and STI exhaust systems. Measuring 3 inches inlet and outlet with 6-inch overall length it absorbs harsh engine vibrations to safeguard manifolds and downpipes. This design cuts stress that causes cracks while boosting longevity across naturally aspirated or turbocharged setups.
Key Features
- Stainless Steel Build: T304 outer braid paired with inner liner resists corrosion endures extreme heat and pressure in performance exhaust
- Inner Braid Liner: Reinforces core structure prevents collapse or kinking during flex maintains shape under boost
- Vibration Isolation: Dampens engine harmonics relieves system stress stops fatigue failure in welds and joints
- Weldable Collars: 3-inch necks simplify custom fabrication secure leak-free connections to tubing or flanges
- Compact 6in Length: Fits tight spaces in downpipe or manifold sections without sacrificing flex range or durability
Product Notes
- Inspect exhaust alignment before welding to ensure even flex distribution
- Suitable for temperatures up to 1600F continuous operation
- Packaged to prevent shipping damage arrives weld-ready
Installation Notes
- Professional installation recommended.
- TIG weld collars to 3in exhaust tubing for strongest seal
- Compatible with standard V-band or ball flange clamps no special hardware required
