V-Band Flange Assemblies

A V-band flange assembly gives you everything for one complete joint: a matched male flange, a female flange and the clamp that draws them together. This collection covers the Vibrant Performance V-band assemblies in stainless steel, aluminum and titanium for turbo outlets, downpipes, intercooler piping and full exhaust systems.

Why buy a matched assembly

V-band flanges from different makers often use slightly different profiles, which can cause leaks. A matched assembly guarantees the flanges and clamp were made to fit each other, so the joint seals metal to metal without a gasket.

Sizes and materials

Assemblies are sized to the outside diameter of the tubing they weld to. Stainless steel is the choice for exhaust and the turbo hot side, aluminum for intercooler and charge piping, and titanium for titanium exhaust systems.

Installing an assembly

Clamp the two flanges together, tack both to their tubes with the clamp installed so the joint stays aligned, then finish weld in short passes to limit distortion. Torque the clamp evenly, tapping around the band as it tightens.

Common questions

Do V-band assemblies need a gasket? No. The male and female profiles seal against each other.

Can I weld a stainless flange to mild steel tubing? Yes, with a filler made for dissimilar metals, such as 309 stainless.

Are these the same as turbo V-band outlets? No. Turbo housings use their own V-band profiles, so choose a turbo-specific flange for a turbine outlet.

What's in This Collection

  • 51 products from Vibrant Performance, priced from $4.99 to $103.99
  • Sizes from 1.5" to 5.75"

  • Free shipping on orders over $150

How to Choose

Match the tube outside diameter and material to the rest of your build. 304 stainless is the most common choice for exhaust, 321 stainless handles the extreme heat of turbo manifolds and headers, titanium saves weight, and aluminum is the go-to for intake and intercooler piping. Wall thickness and bend radius matter when you need parts to fit together cleanly.

More Questions

Do I need to back purge stainless when welding?

Yes. Back purging with argon keeps the inside of the weld from sugaring, which gives you a stronger, cleaner joint.

Can I mix stainless and mild steel?

You can weld them together with the right filler, but the joint can rust over time. For best results keep the system one material.
