Pontiac, a perfect choice of thousands of motorists who are looking for comfort, power and safety features. Pontiac is globally known for their flawless quiet engines which offer great mileage and superior performance for miles and miles of drive. Such an engine quality of the Pontiac is only possible by its exhaust system. Of all constituent of the exhaust system, one of the important performance parts is exhaust manifold. The term "manifold" has come from an old English word manigfeald (manig-many; feald-fold) meaning folding of multiple inputs & outputs together. Pontiac Exhaust Manifolds are one of the easiest bolt-on auto-parts you can use to improve your engine's performance.
Pontiac exhaust manifold equals a free flowing passage, explicitly designed from high grade materials. The high grade materials may vary from tubular steel, lightweight aluminum or cast iron or nodular iron. It is because of such a heavy construction of manifold that engine starts breathing and exhaust starts emitting every moment at a high pace. Pontiac exhaust manifold are crafted in a way to decrease the flow resistance i.e. decrease in back pressure and increase the volumetric efficiency of an engine for high power output gain. Different configurations of manifold enables it to fit the type of engine your Pontiac has like Pontiac Firebird(1977-1981) is equipped with Exhaust manifold located near the passenger side, Pontiac Phoenix(1978-1979) is equipped with Exhaust manifold located near the driver side, etc.
Pontiac exhaust manifold efficiently gathers the exhaust gases from different exhaust parts and routes them to the exhaust pipe. The exhaust pipe relays these gases to the catalytic converter which then changes the toxic gases into their relatively less toxic counter-parts. So, in short Pontiac exhaust manifold's prime responsibility is to collect all the gases and route them into a single pathway, and that is towards the tailpipe. Pontiac exhaust manifold is like a network of tubes situated at the exit passage of each cylinder. The basic engineering design of Pontiac exhaust manifold and their count depends on the number of cylinder head used in your Pontiac. For example single exhaust manifold are of great use in the vehicles with linear engines. Two exhaust manifolds are meant for V-shaped engines, and each manifold is mounted on each cylinder head.
Every one of us is scared to death, so why to take a risk of your own. It's better to take precautions rather than sitting idle or abusing the brand or dealer or your Pontiac. While driving your beauty beast, if you ever heard a ticking, popping or tapping sound then definitely your Pontiac's exhaust manifold is leaking. So, rather than avoiding such situation one must take it as a serious issue and must rush for an immediate replacement of Pontiac exhaust manifold, before it is too late.
What causes Pontiac Exhaust Manifold to fail?
- Corrosion of cylinder head
- Corrosion of manifold or header or extractor
- Leakage in manifold
As the Pontiac exhaust manifold is not made to last, a regular visual inspection is needed to avoid its sudden damage/ decay. A properly maintained Pontiac exhaust manifold in a top shape aims to gain maximum power output. If you want to upgrade and improve the performance of your exhaust system then the High performance Pontiac exhaust manifold is the right choice.
