Back Pressure in Royal Enfield
“Back pressure is the pressure drop in the flow of gases from engine to exhaust. The less power engine has to spend making pressure to push the gases from exhaust output, the more power it can send to the wheels�.
The term back pressure is misleading as the pressure remains and causes flow in the same direction, but the flow is reduced due to resistance. For example, an automotive exhaust muffler with a particularly high number of twists, bends, turns and right angles could be described as having particularly high back pressure.
The exhaust having maximum bends will have the higher back pressure resulting in negative effect on engine efficiency resulting in a decrease of power output that must be compensated by increasing fuel consumption. Less back pressure makes engine able to transfer maximum power to wheels and keeps it less heated up.
The motorcycle’s exhaust pipe is connected to the cylinders in the engine. When the engine is operating, it circulates gas throughout the system. The gas expands as it circulates through the engine, then finds its way into the cylinders. Some of the gas is not expelled out of the exhaust pipe, and it then creates exhaust back pressure. All of the gas pressure should leave out of the cylinders and into the exhaust pipe at a constant rate. If the rate is thrown off balance, then you have the result of exhaust back pressure in your motorcycle. Many believe that there is no effect on your engine when motorcycle exhaust back pressure is formed. Either way, it is not normal for exhaust back pressure to occur.
Back pressure caused by the exhaust system of an automotive four-stroke engine has a negative effect on engine efficiency resulting in a decrease of power output that must be compensated by increasing fuel consumption.

Free Flow silencers has less back pressure than that of stock silencers that is why we bulleteers prefer louder sound but the fact behind it that a free flow silencer helps in less heating up of engine and louder sound as we alwayz want.
i do have 1965 G2 engine bullet original….
If we replace new design silencer by old one, then is there any affet on engine performance / milage?
