* Reduced flow restriction: A dual exhaust system has two pipes instead of one, which means there is less restriction on the exhaust flow. This allows the engine to breathe more easily and produce more power.
* Better scavenging: Dual exhaust pipes help to scavenge the exhaust gases from the cylinders more effectively. This means that there is less residual exhaust gas in the cylinders, which allows for a more complete burn of the air/fuel mixture.
* Improved sound: Dual exhaust pipes can also improve the sound of your car. A dual exhaust system typically produces a deeper, more aggressive sound than a single exhaust system.
