Headers are never fun to install unless its on a truck so there was an understandable amount of disassembly to the car to get them in. Induction compression combustion and exhaust the never-ending cycle that keeps the heart of all internal combustion engines running.

An exhaust header makes it easier for the cylinders in a car to push out exhaust. Exhaust Headers Exhaust Manifolds. This means more air in the combustion chamber and all injected fuel can be fully utilized resulting in a much more efficient engine.

That is why the exhaust header is typically made of cast iron or some other high-heat resistant material. Save Off Dealer Prices. Exhaust headers vs exhaust manifold which is better.

Aftermarket exhaust manifolds look and fit just like the exhaust manifold that came on the car when it was new with similar flow characteristics. The small gain in performance facilitated by an exhaust header is important to high performance drivers who often make other modifications to their vehicles in order to increase speed. An exhaust header has individual tubes for each exhaust port allowing each exhaust pulse to flow unobstructed from the cylinder head.

An exhaust header is an after market automotive part designed to improve vehicle performance. An exhaust manifold is an OEM-style part. When your engine expels exhaust gases they are first sent to your manifold and then to the rest of the exhaust.

All headers consist of three main components. We prefer to use CNC machined header flanges made from 304ss. The primary tubes which are welded to the flange and transport the exhaust gases.

It is the first place out of the combustion chamber where very hot exhaust gasses pass. JEGS offers a wide selection of exhaust manifolds and exhaust headers from brands such as Hedman Hooker JBA Pace.

Aftermarket exhaust headers are typically made from stainless steel which is great to prevent rusting and better yet they are lighter. 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 which reduces restriction and increases. The most sophisticated of these and the most well thought out of this type are found on performance cars.

Exhaust headers are lighter. Custom headers are also installed for aesthetic appeal. The starter and oil filter need to be removed and the.

Headers are made of longer thinner steel tubing. Ad High Performance Headers For Cars Trucks. Dyno testing has shown that a poorly fit portheader interface can result in a 2-5 loss of power.

13 Exhaust systems--Every street rod shall be equipped with an exhaust system that is free of leaks including the exhaust manifolds including headers the piping leading from the flange of the exhaust manifolds and the tail piping. 30 Day Return Policy.
