Vibrant SS Turbo FLEX Coupling with Interlock Liner 3in inlet/outlet x 4in long – Universal
This Vibrant Performance flex coupling connects 3-inch exhaust sections in turbocharged vehicles reducing vibration transfer from the engine. It fits universal applications including custom downpipes manifolds and exhaust systems on cars trucks with forced induction. The design absorbs flex and movement to prevent cracking and extend component life.
Key Features
- Stainless Steel Construction: T304 stainless steel bellows braid and fittings resist corrosion high heat and boost pressure for long-term reliability in performance exhaust
- Interlock Liner: Braze-welded interlock stainless liner prevents collapse under high boost maintains airflow and structural integrity during extreme conditions
- Vibration Isolation: Decouples engine vibrations from exhaust system minimizing stress on manifolds downpipes and hangers to avoid premature failures
- Precise Dimensions: 3-inch inlet/outlet inside diameter 4-inch overall length 4.125-inch outside diameter supports tight routing in turbo setups
- High Flex Capability: Supports up to 7-degree max bend angle handles thermal expansion and motion without fatigue
Product Notes
- Clamps and flanges sold separately use T-bolt or V-band style for secure connection
- Inspect regularly for exhaust leaks ensure proper alignment during install
- Packaged for protection ships in 5in x 5in x 5in box
Installation Notes
- Professional installation recommended.
- Torque clamps to manufacturer specs avoid over-tightening to preserve flex
- Compatible with 3-inch V-band flanges and T-bolt clamps common in turbo exhaust
