What is the best material for headers?

“The most common materials used in racing headers are mild steel and stainless steel,” said Roman. “Inconel and titanium are also used, though we do not recommend titanium for most automotive drag race applications. Mild steel is the least expensive option and the most readily available.

What are engine headers made from?

“Headers” are usually made of tube steel and have much longer runners for the individual ports before merging together. Depending on the type of engine, the individual runners may be designed to be all the same length, or varying lengths.

What are exhaust headers made of?

The most common types of aftermarket headers are made of mild steel or stainless steel tubing for the primary tubes along with flat flanges and possibly a larger diameter collector made of a similar material as the primaries.

Are ceramic coated headers better?

A ceramic header coating also provides protection against the corrosive materials in the exhaust. Ceramic is a highly durable substance that resists corrosion and stands up to a large amount of abuse. Properly coated headers are thus much more durable than the thinner pipes of uncoated headers.

What coating is best for headers?

Ceramic Coated Headers
Ceramic Coated Headers are the best option for performance and durability. Most people like the way they look and the finish will last longer than paint.

What metal is used for exhaust manifold?

Cast iron
Cast iron is used for the exhaust manifold (stock). Aluminized steel is often used in aftermarket exhaust systems.

What material is a turbo manifold made of?

321 tubing, stabilized with titanium, is an excellent choice for most turbo applications due to the increased material strength at high temperatures. For systems with higher EGTs one should consider using Inconel.

Is Cast Iron good for turbo manifold?

It is to be noted that cast iron turbo manifolds are stronger than welded manifolds. Even a properly welded turbo manifold, will fail much sooner than a cast iron manifold. This is just the nature of casting vs welding. The Turblown Cast Rx7 turbo manifolds are made from 347SS.

Is it worth ceramic coating a turbo?

As for turbo and supercharger components, the application of a high-temperature ceramic coating helps maintain lower surface and internal temperatures, and thus reduces the risk of engine heat-soak issues.

Is ceramic coating Turbo worth it?

Improve Efficiency First, because ceramic coated headers help keep the heat in the exhaust gas rather than letting it seep out, preventing heat leak speeds the expulsion of exhaust out the tailpipe. This decreases back pressure, which improves the efficiency of the engine.
