Vibrant Performance T304 SS 4 Bolt Flange for 4in O.D. Oval Tubing - Universal Custom Exhaust Fit

Vibrant Performance 13177S flange joins 4-inch outer diameter oval tubing in custom exhaust systems for cars trucks and race vehicles. T304 stainless steel build resists corrosion and handles extreme heat for long-lasting performance. 4-bolt design forms secure leak-free connections in high-flow turbo downpipes Y-pipes and full exhaust setups.

Key Features

  • T304 Stainless Steel: Resists rust and withstands extreme heat for reliable service in harsh exhaust environments
  • 3/8in Thickness: Heavy-duty plate endures high pressure and resists warping under boosted high-flow conditions
  • 4-Bolt Configuration: Provides even tension for airtight seals that preserve exhaust flow and power
  • 4in O.D. Oval Fit: Precision matches standard oval tubing for easy bolt-on integration in custom builds
  • CNC Precision: Machined holes accept 3/8in exhaust bolts for fast accurate assembly without modifications

Product Notes

  • Sold individually bulk packs of 5 available for shops and large projects
  • Works with turbo downpipes Y-pipes and complete custom exhaust systems
  • Confirm tubing measures 4in outer diameter before purchase

Installation Notes

  • Professional installation recommended.
  • Bolt holes sized for 3/8in-24 exhaust studs or bolts
  • Apply anti-seize compound and exhaust gaskets for maximum sealing

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...
