Why do some cars have dual exhaust pipe?
Engine is like a huge vacuum pump, sucks in air and fuel. An engine like the one in a car has four stroke: Intake, compression, combustion and exhaust. Once the air and fuel are pulled into the engine (intake), the piston comes up to compress the mixture to make it more volatile (compression). The spark plug fires and causes an explosion in the cylinder (combustion). However, not all of the fuel and air is used. This leftover mixture must make its way out of the engine to make room for a new wave to start. This is the exhaust stroke – the leftover gas and air are forced out of the cylinder through the exhaust valves, into the exhaust manifold and out through the exhaust system.
Dual exhaust systems will indeed increase your car's performance. The final stroke in an engine's combustion cycle is the exhaust stroke. The engine has to push out all the used-up air and leftover fuel bits before taking in new air and fuel to be ignited.
Adding an additional exhaust system, especially in V-6(having six cylinders) and V-8(having eight cylinders) engines where you can have one system per bank of cylinders, gets more of the used-up stuff out the back-end faster. The faster and more efficiently the cylinders are cleared, the faster the cycle can start all over again, and the faster the engine can propel.
Adding a dual exhaust system to a smaller engine, like a four-cylinder for instance, won't make much of a difference.
