What Does A Baffle In An Exhaust Do

Motorcycle baffles AKA exhaust baffles are specially designed tubes – inserted into a motorcycle’s exhaust to quiet down the engine sound. Engine sound (any sound really) travels in waves. The walls surrounding a baffle tube are made to bounce sound waves – causing them to reverse, crash into each other and cancel out.Jan 9, 2021

Do baffles increase horsepower?

Baffles are a relatively small device – located at the end part of an exhaust. Replacing or removing them will not impact the air-fuel ratio on your motorcycle as much. Which means, you won’t really feel much difference in terms of horsepower or torque.

How does baffle size affect sound?

To reduce the noise, manufacturers fit baffles into the exhaust system. Larger baffles are usually louder because they are more hollow with less obstacles – allowing the sound waves to travel freely (less restrictive).

What happens when you remove baffle?

Removing the baffles will change how the engine runs. It will usually cause the engine to run leaner (less fuel), and a lean mixture burns much hotter that can cause damage. Removing the baffles will also mess up the power curve of the motor. Usually loosing power down low and gaining a slight amount up top.

On the flip side, long baffles with large holes can minimize noise without hindering the high-performance outflow.

Are car speaker baffles worth it?

Speaker baffles are definitely worth it. They minimize mechanical vibrations and the diffraction of sound waves to create a more honest reproduction of sound and improve off-axis frequency response.
