How to Make a Car Sound Roar?

[VanDakota]

Modifying the mid-section of the exhaust system can alter the sound of a car's exhaust. Below are the relevant details: 1. Main benefits of exhaust modification: Enhancing the engine's power and accelerating the speed at which the engine RPM rises, thereby improving the vehicle's acceleration performance. The original exhaust system, constrained by environmental requirements, typically has significant exhaust resistance, commonly referred to as high 'back pressure.' This creates resistance to the engine's operation, preventing the RPM from rising quickly. It also results in incomplete expulsion of exhaust gases from the engine cylinders, affecting the intake of fresh air for the next combustion cycle, which in turn prevents the engine from delivering its full potential power. 2. Reducing exhaust resistance: A smoother exhaust flow has the added effect of making the exhaust sound closer to that of a racing car's roar, as racing cars use straight-through exhaust systems with minimal resistance.
