Performance Headers

Shorty & Long Tube Headers, Polished & Plated

The easiest way to get more horsepower and torque from your engine is to increase intake air flow and exhaust flow. Factory air intake and exhaust systems are compromises, but if you want to go a step further, consider a set of headers. Headers install between the cylinder heads and exhaust pipes, in place of your factory exhaust manifolds. They are constructed of individual tubes, one for each exhaust port, that all meet in a larger tube called a collector.

Your stock exhaust manifolds were probably designed with more importance paid to how they fit in the engine compartment. They’re restrictive because all of the exhaust pulses dump into the same small space. In contrast, an exhaust header has individual tubes for each exhaust port. And once the exhaust pulse leaves the port, it flows into a larger space because headers also have larger diameter tubes that are usually mandrel bent for gradual radius bends.

We aim to provide our customers with the finest Performance Headers the industry can offer, which is why we accept no compromise when it comes to the quality. Created by the most reputable names in the industry, such as MagnaFlow, Gibson, Borla, Flowmaster, BBK, Banks, aFe, DC Sports, Weapon-R, Rugged Ridge, Spec-D the Performance Headers we've gathered for you feature precise design and everlasting durability.

Besides less restriction, some headers can also increase performance because of the “scavenging” effect. When an exhaust gas pulse exits a header tube into the collector, a negative pressure wave is created that travels back up the header tube to the exhaust port during valve overlap. This negative pressure helps pull any remaining exhaust gas from the cylinder and also helps draw the incoming intake charge into the cylinder. This is very beneficial to engine performance but the tubes must be long enough for it to be effective during a useable rpm range.

Headers come in a number of configurations, including short tube, or “shorty”, and long tube. In general, it’s usually easier to achieve the aforementioned scavenging effect with long tube headers, but there are also shorty headers with equal length tubes. Long tube headers require that the exhaust pipes be cut and flanges attached that will connect with the header collector. The tubes on short tube headers generally fit more easily in the engine compartment and some are designed to connect to the existing exhaust pipe flange, so no cutting or welding is necessary.

On most headers all 4 pipes end together in the collector, but there are also so-called “tri-y” headers. On a tri-y header, the opposite cylinders in the firing order are paired in a short “Y”, and then the Ys combine in the collector. Today, most headers are constructed from stainless steel, or heavy-duty plain steel that’s been chrome plated or ceramic coated for durability. Stainless steel headers will not rust but they will usually turn blue near the head flange. Ceramic coatings are durable and can withstand higher temperatures.

Guides & Articles
Headers are installed because the stock exhaust manifolds usually flow poorly. An exhaust header has individual tubes for each exhaust port, allowing each exhaust pulse to flow unobstructed from the cylinder head. The tubes on headers are usually larger in diameter than the runners on an exhaust manifold and the tubes are mandrel bent for gradual radius bends.
