Can Modified Exhaust Sound Pass Vehicle Inspection?

[KadenDella]

Modified exhaust sound cannot pass vehicle inspection. Introduction to Car Exhaust Sound: Car exhaust sound refers to the roaring noise caused by the rotation of the car engine. Cars equipped with V10, V12, or even V16 engines can make many people turn their heads when they roar. However, in addition to the engine itself, some modified or specially tuned exhaust systems can also produce captivating exhaust sounds. Factors Determining Exhaust Sound: Material type, muffler type, resonator length, flow restriction, and exhaust tuning. Of course, the main factor is the engine - the sound of a 4-cylinder engine is completely different from that of a V12 engine. But after tuning, both can produce heart-throbbing exhaust sounds. For example, the exhaust pipes of Mercedes-Benz AMG and Lexus LFA models, after special tuning, produce sounds referred to as "the roar of angels."
