What can be the result of a poor exhaust flow in terms of torque?

A poor exhaust flow can lead to decreased torque output because it affects the engine's ability to efficiently expel exhaust gases. When exhaust gases are not effectively removed from the combustion chamber, it creates back pressure that hinders the intake of fresh air and fuel for the next combustion cycle. This restricted flow can prevent the engine from achieving optimal combustion, which in turn decreases the engine's power and torque characteristics.

In an engine, torque is critical for acceleration and overall performance. Therefore, when the exhaust system is compromised, the engine operates less efficiently, resulting in reduced torque. A properly functioning exhaust system is essential to maintain the necessary airflow that supports combustion and torque production.
