Is the exhaust sound related to the engine?

[Gemma]

The exhaust sound depends on the material, diameter, and design of the car's exhaust pipe. The exhaust pipe has a significant impact on the sound. Characteristics of the engine itself: It affects the exhaust sound, which is closely related to the engine's displacement, number of cylinders, intake form, etc. The exhaust pipe consists of three sections: They are the front pipe, mid pipe, and rear pipe. The front pipe is the exhaust manifold, which is connected to the engine. The mid pipe runs through the entire chassis, and the rear pipe is the part near the car's rear bumper. The mid pipe and rear pipe have a significant impact on the exhaust sound, while the front pipe has a greater impact on the engine's performance. This is because there is an important component on the front pipe called the three-way catalytic converter. The three-way catalytic converter is used to purify exhaust gases, but it can obstruct the engine's exhaust, thus affecting power in the high RPM range.
