Stainless Bros

Building your own exhaust or manifold, or looking for finished headers for your project? Stainless Bros focuses on stainless steel exhaust components for fabrication and performance. Here you’ll find tubing, bends, collectors, flanges and headers that make it easier to build an exhaust that fits your engine precisely.

Stainless steel for fabrication and performance

Stainless Bros is well known among fabricators and engine builders who work with stainless steel exhausts. The range is built around the components you need when building an exhaust or manifold from scratch: tubing in many sizes, mandrel bends and collectors that provide smooth flow. Stainless steel handles high temperatures and corrosion better than mild steel, which makes it a popular choice for both turbocharged and naturally aspirated engines.

Stainless Bros’ key products

Mandrel bends and straight tubing are the foundation of many fabrication projects. Mandrel bending keeps the tube diameter consistent through the entire bend, so flow is not restricted. Merge collectors join several primary tubes into one and are a key part of a header or turbo manifold. The range also includes flanges, V-bands, slip joints and finished headers for selected engines. See each product for dimensions, material and fitment.

Frequently asked questions

What is the difference between mandrel-bent and crush-bent tubing?

In mandrel bending, the tube is supported from the inside while it is bent, so the diameter stays the same through the bend. Crush-bent tubing is often pinched in the bend, which reduces flow.

What is a merge collector?

A merge collector joins the primary tubes of a header or manifold into a single tube. Its shape and angle affect how the exhaust pulses meet, and therefore the engine’s character.
