Vibrant 3.02in ID x 4.00in Long 321SS Electro Polished Motorsport Bellows w/Neck & Liner (04-21 Subaru STI, 03-09 Nissan 350Z, 09-20 Nissan 370Z)

Vibrant 69835 motorsport bellows deliver reliable flex in high-performance exhaust systems. Designed for vehicles like 2004-2021 Subaru Impreza WRX STI, 2003-2009 Nissan 350Z, and 2009-2020 Nissan 370Z, it handles engine vibration and thermal expansion. This 321SS construction ensures long-lasting performance under extreme conditions.

Key Features

  • 321 Stainless Steel Build: Withstands temperatures up to 1600°F and resists cracking from repeated flexing.
  • Electro Polished Finish: Smooth surface repels exhaust residue and corrosion for extended service life.
  • 3.02in Inner Diameter: Secure fit over standard 3in exhaust tubing without adapters.
  • 4.00in Length: Balances flexibility and rigidity to isolate drivetrain movement.
  • Neck and Liner Design: Provides airtight seal and minimizes exhaust turbulence for better scavenging.

Product Notes

  • Ideal for turbo downpipes and custom exhaust fabrication.
  • Inspect clamps regularly to maintain seal integrity.
  • Packed in protective sleeve to prevent handling damage.

Installation Notes

  • Professional installation recommended.
  • Use stainless steel 3in V-band or U-bolt clamps for secure attachment.
  • Torque clamps to 45-50 in-lbs and align necks concentrically.

Fabrication

Fabrication

Fabrication parts and materials provide the raw components needed to build, repair, and modify custom exhaust systems, turbocharger plumbing, intercooler piping, fuel system lines, oil routing, and engine bay heat management on performance and competition vehicles. Stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, pie cuts, flanges, merge collectors, V-band clamps, O2 sensor bungs, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, and welding supplies are the backbone of any serious custom fabrication project. Professional fabricators, race team mechanics, and advanced DIY builders who want full control over exhaust routing, charge pipe layout, or fuel system plumbing choose raw fabrication materials rather than pre-bent kits because custom fabrication allows fitment solutions that no universal kit can accommodate. Brands including Vibrant Performance, Ticon Industries, Stainless Bros, Radium Engineering, Fragola, and DEI provide th...

Flanges

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...
