What components must all motor vehicles have as part of their exhaust system?

All motor vehicles are required to have essential components in their exhaust system to ensure proper operation and compliance with safety and environmental regulations. A properly attached exhaust pipe, muffler, and tailpipe are vital because they work together to channel exhaust gases safely away from the engine and the vehicle's interior, reduce noise produced by the engine, and ensure that harmful emissions are managed effectively.

The exhaust pipe directs the flow of exhaust gases, while the muffler reduces the noise, and the tailpipe is the final section that releases the gases into the atmosphere. Collectively, these components help in minimizing pollution and meeting emission standards, making them necessary for all vehicles.
