Automotive Exhaust System Market Size

Automotive Exhaust System Market size was valued at USD 118.06 billion in 2024 and is expected to cross USD 244.84 billion by the end of 2037, expanding at more than 5.9% CAGR during the forecast period i.e., between 2025-2037. In the year 2025, the industry size of automotive exhaust system is estimated at USD 123.54 billion. The growth of the market can primarily be attributed to the growing demand of automotive exhaust system owing to the fact that transportation holds the largest share of greenhouse gas (GHG) emissions worldwide. For instance, the transport sector was responsible for 25% of greenhouse gas emissions in 2020.

Automotive exhaust system collects the exhaust gases from the cylinders, removes harmful substances, and reduces the level of noise. It also discharges the purified exhaust gases at an appropriate point of the vehicle away from its occupants. Depending on the engine, the automotive exhaust system can consist of one or two channels. With every internal combustion engine producing the exhaust noise as well as stringent policies regarding the noise limits, the demand for automotive exhaust systems is on the rise amongst the automobile manufacturers, which in turn, is expected to create massive revenue generation opportunities for the key players operating in the global automotive exhaust system market during the forecast period. For instance, as per the Environment Protection Rules 1986 (EPR), the noise limits of all passenger and commercial vehicles at the manufacturing stage should range from 81 dB to 90 dB.
