Exhaust Header

Exhaust Header – more power and torque

An exhaust header is one of the key components of the exhaust system and has become almost essential in motorsport and the tuning scene today. Installing an exhaust header increases engine power while also improving torque. Power gains of up to 5% are commonly mentioned. In addition, the engine runs more smoothly and fuel consumption can be reduced. These are just some of the advantages an exhaust header offers compared to a standard exhaust manifold. Would you like to have an exhaust header installed or are you looking for a suitable model? At TA Technix, we are happy to help. We offer a wide range of TA Technix exhaust headers known for their high quality and popularity among tuning enthusiasts. Rely on our service, because an exhaust header must always be precisely matched to the specific engine.

What is an exhaust header?

An exhaust header is an optimized exhaust manifold. The optimization lies in pipe lengths, diameters, and routing that are precisely matched to each individual cylinder. Thanks to this special design, the exhaust header is able to extract exhaust gases from the cylinders more quickly (at approximately 1,200 km/h), preventing exhaust gas residues. During the next cycle, more fresh air enters the combustion chamber. The exhaust header therefore utilizes the principle of interference. Because the exhaust gases no longer have to be forced out by the piston, fewer stagnant gases remain.

How does an exhaust header work?

Let’s take a closer look at how an exhaust header—usually made of stainless steel—works. A conventional exhaust manifold is mounted directly on the engine and is responsible for directing exhaust gases away. It is typically designed to be very compact to save space in the engine bay, which results in a noticeable loss of power and torque. Why? Because the exhaust gases cannot flow efficiently enough to increase performance. This is where the exhaust header comes into play.

The exhaust header works based on various physical principles such as the Venturi effect, interference, and oscillating gas columns. When the exhaust valve opens, exhaust gases are guided through the manifold into the exhaust system. Oscillating gases then meet residual gases, which are synchronized by these oscillations. This creates the characteristic exhaust sound. In an exhaust header, the exhaust gases flow sequentially into the manifold. These gases generate negative pressure, effectively drawing the mixture out of the cylinder. The Venturi effect creates a suction effect that makes exhaust removal even more efficient. The exhaust header channels the gases through the pipes without residue and uses the reflected pressure waves to create additional negative pressure, improving exhaust flow. Ultimately, this interaction allows the exhaust gases to be transported through the exhaust system at a higher velocity.

How much power does an exhaust header add?

Optimizing exhaust gas flow with an exhaust header results in increased power and torque. Depending on the model and the initial setup, the gains may vary. In some cases, installing an exhaust header can increase output by around 40 hp. However, the rest of the exhaust system must also be matched to the header. For best results, the exhaust header should be combined with a sports exhaust or a high-performance catalytic converter. Conversely, this means that significant power and torque gains are unlikely if the exhaust header is installed on an otherwise stock vehicle.
