If a truck's exhaust pipe is broken or deteriorated, what direct consequence does it mainly cause?

Question

DentroTest · Accepted Answer

The exhaust system includes silencing elements whose main task is to dampen and dissipate the sound waves generated by the constant explosions of combustion in the engine cylinders. If the exhaust pipe breaks, cracks or deteriorates, the gases escape to the outside without being properly silenced, which causes a considerable increase in noise pollution. For this reason, the General Traffic Regulations (Article 7) prohibit driving with the so-called 'open exhaust' or with incomplete, unsuitable or deteriorated silencers. This fault does not directly increase fuel consumption or the gross generation of gases in the combustion chamber.
