How Racing Downpipes and Air Intakes Contribute to Performance

There are two popular modifications when it comes to enhancing the performance of a vehicle and these are racing downpipes and air intakes. They can boost the efficiency and power of a vehicle so that you can have an improved driving experience.

Racing downpipes can replace

The restrictive factory downpipes that you can find in many vehicles. These are aftermarket components and they are part of the exhaust system of the vehicle that will connect the turbocharger or exhaust manifold to the rest of the exhaust system. These tend to have larger diameters and smoother bends so that more efficient exhaust gas flow can be facilitated.  The main function of PH racing downpipes is reducing the backpressure in the exhaust system. Backpressure can occur when there is a restriction of exhaust gases. Due to this restriction, the exit from exhaust gases will slow down. High back pressure can limit the performance of the engine. This will make it harder for the engine to expel the exhaust gases and also reduce the ability of the engine to intake fuel and fresh air. There are less restrictive catalytic converters in racing downpipes and sometimes these will not have any catalytic converters at all. The latter can affect emissions compliance so you will need to check this beforehand. The downpipes will improve the breathing of the engine by allowing exhaust gases to flow freely. And this can provide you with many performance benefits.

When backpressure is reduced,

The engine will be able to efficiently expel the exhaust gases. And with this improved flow, the engine is able to take in more fuel and air. This will lead to increased combustion efficiency and power. If you have a turbocharged engine, the turbocharger efficiency can be significantly enhanced by racing downpipes. The turbocharger is able to spool up efficiently and faster when restriction in the exhaust flow is reduced. This will lead to a faster boost response. There will also be improved throttle response due to reduction in backpressure. The engine is able to react quickly to the inputs of the driver so that a more immediate driving experience can be provided.

Air intakes are designed to bring air into the engine.

There are many types of air intakes that include cold air intakes and short ram intakes. Cold air intakes are popular for performance enhancements as they will draw cooler air from outside the engine bay. The cooler air is more dense and will have more oxygen. The objective of an upgraded air intake system is to increase the volume and quality of air entering the system. The stock air intake systems can limit the breathing capabilities of the engine. But these limitations will be addressed by aftermarket air intakes as they will provide a more direct path for air to reach the engine. As restrictions in the intake path are reduced, more air will flow into the engine so that it can mix more air with fuel. This will lead to efficient combustion and more power.
