Now, getting back to putting something into the curved exhaust header: These straight flow thru silencers often offer removable baffles or pierced tubes to quiet the exhaust further but please notice, even with these installed, the large volume of the silencer does provide space for the exhaust to expand into. This is much less effective at reducing noise than the silencers with torturous path design but it does quiet the sound a bit. They do this by having a perforated pipe that allow some of the high pressure gas to enter their larger bodies or housings and release this gas back thru the perforated pipe when the pulse from the engines exhaust has passed thru. Silencers with straight flow thru designs have almost no restriction but they still reduce the noise of the exhaust. At very high engine speeds on the other hand the restriction will decrease the total power the engine can produce.

On the negative side of this, the silencer still does create a restriction in the gas flow.Īt normal riding speeds, the restriction does not have a negative effect on the engines power.

The silencer then allows this expanded (and slowed) gas to travel thru a torturous path created by a series of baffles and/or perforated walls to restrict the flow so it enters the atmosphere at a slower, more uniform speed. The difference is, little noise is produced because it is all contained within the metal housing. If a silencer is installed, the gas will still expand when it reaches the end of the pipe because the much larger silencer body provides increased room for it. If no silencer is installed, this gas will rapidly expand into the environment with a very loud noise when it reaches the end of the pipe.

Its pressure is reduced slightly as it passes down the exhaust pipe because of the unrestricted passageway and some loss of heat but its velocity and pressure is still very high. The exhaust exits the cylinder as a high pressure blast of hot gas. The main idea behind removing the silencer to improve power is to remove the restrictions on the gas flow from the engine to the atmosphere.īefore going on, let me give a simplified explanation of how the factory OEM silencer works. The effect will be worse than leaving the factory silencer installed on the bike. IMO, anything you place into the exhaust pipe will greatly lower the performance of the engine.
