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

Start with tubing (304 or 321 stainless, titanium, or aluminum) in the right diameter and wall thickness, then add mandrel bends, flanges, V-bands, and clamps to complete the joint work. AN plumbing follows the same pattern: match dash size to horsepower target, pair the right hose (PTFE or CPE) with matching hose ends, and use adapters, bulkheads, and distribution blocks to route fuel, oil, and coolant cleanly. Shop by material (stainless, titanium, aluminum), fitting type (AN, ORB, NPT), diameter, or brand (Vibrant, Ticon, Stainless Bros, Radium, Fragola, DEI, ATP). ...

Flanges
Exhaust flanges are the bolted connection points where exhaust manifolds mate to downpipes, where sections of exhaust pipe join at catalytic converters and muffler inlets, and where aftermarket headers connect to factory or custom collector sections, making flange quality and correct material specification critical for maintaining leak-free exhaust connections under the extreme temperature cycling that performance exhaust systems experience. Flange warping and gasket failures at exhaust connection points are among the most common exhaust leak sources on both stock and modified vehicles, as the thermal expansion differences between the flange material and the connected pipe cause progressive face distortion over time that breaks the gasket seal. Performance exhaust builders use thick-cut mild steel, stainless steel, or titanium flanges in precise O.D. profiles matched to their pipe diameter to ensure the clamping surface remains flat through hundreds of heat cycles. This collection c...
