Vibrant SS Flex Coupling with Inner Braid Liner 1.75in inlet/outlet x 6in flex length for Subaru WRX STI Nissan 240SX
Vibrant Performance Standard Flex Couplings with Inner Braid Liner deliver smooth exhaust flow while maintaining flexibility to handle engine vibration and movement. This universal stainless steel part fits any vehicle exhaust system using 1.75 inch piping including Subaru Impreza WRX STI 2002-2009 Nissan 240SX 1995-1998 and custom turbo downpipes. The inner braid liner shields the bellows from high temperature exhaust gases to extend service life and stop whistling from high velocity flow.
Key Features
- Stainless Steel Build: T304 construction resists corrosion and withstands extreme exhaust temperatures for long lasting performance
- Inner Braid Liner: Interlock design protects bellows from heat exposure and fatigue preventing early failure in demanding applications
- Flex Length 6in: 6 inch bellows section with 8.5 inch overall length absorbs vibration and thermal expansion without restricting flow
- 1.75in Inlet/Outlet: Precise slip fit ends weld directly to 1.75 inch exhaust tubing for seamless custom exhaust fabrication
- Whistle Elimination: Smooth inner surface handles high velocity exhaust gases quietly without turbulence or noise
Product Notes
- Suits high performance turbo and naturally aspirated exhaust systems requiring flexible sections
- Regular inspection ensures optimal sealing and performance over time
- Packaged to arrive ready for immediate fabrication or installation
Installation Notes
- Professional installation recommended.
- TIG weld ends to 1.75in OD exhaust pipe for secure leak free connection
- Compatible with standard exhaust fabrication hardware and V-band flanges
