The exhaust manifold on your vehicle is responsible for routing the escaping exhaust gases away from your engine and towards your exhaust pipes. If your exhaust manifold fails for any reason the exhaust vapors could get caught in your system and causes backpressure in your engine. This backpressure can then clog your engine's ability to breath, which results in decreased power production. Before this happens you need to install a quality Replacement Exhaust Manifold. Depending on the exact style and specifications of your engine this manifold can either be crafted from cast iron or tubular steel. And depending on the type of engine you have the design of the Replacement Exhaust Manifold will be different. Some manifolds feature individual pipes for each cylinder while others are crafted as a single unit. Another great feature of a Replacement Exhaust Manifold is tubing design. If the tubes are mandrel-bent your exhaust gases are given a less restrictive path to escape which increases airflow and lets your engine produce more horsepower, and torque. The right manifold can even give you increased fuel economy. With so much performance at stake this unit is one part that you should never suffer from damage.
