   10 wrz 2024 · 2. What is Back Pressure? Back pressure is a common topic in exhaust discussions. Contrary to popular belief, a muffler does not create the necessary back pressure for your engine. Instead, back pressure naturally occurs as exhaust gases move through the system, especially at higher RPMs.

   What is Exhaust Back Pressure in IC engine? Exhaust back pressure is the excessive pressure building at the engine exhaust because of the flow restrictions to the exhaust gases offered by the exhaust system. It opposes the movement of the piston during the exhaust stroke thus causing the loss of power at the crankshaft and improper scavenging.
