Does a baffle reduce noise?
Baffles are an absorptive board or sound barricade that can be placed around or between acoustic sources to provide sound isolation or deadening and reduce acoustic leakage. They are an effective noise barrier when applied to walls and ceilings in building interiors to absorb sound energy and thus lessen reverberation.
Does removing baffles hurt engine?
It is possible to damage your engine by removing baffles from your exhaust. It is possible to damage your engine by removing baffles from your exhaust. Removing baffles from the exhaust provides for a freer flowing exhaust, causing your exhaust to become louder and flow more air or flow air faster.
What does a baffle do in an exhaust?
Exhaust baffles are metallic chamber parts that are acoustically tuned and fit onto the exhaust pipe’s muffler. They function to cancel out or muffle the loud noise created from the exhaust pipe. Most motorcycles come with a standard baffle or muffler required by law to reduce the engine’s natural noise levels.
What is the purpose of a baffle in an exhaust?
Exhaust baffles are used primarily to reduce the loud noise generated by a vehicle’s engine. Such loud noises are a nuisance and are characterized as noise pollution.
Do you have to retune after removing baffles?
Removing your baffles will likely require a retune…that really messes with the back pressure. If you listen to some other mufflers and inquire as to the manufacturer of some that you like, you’re more likely to better match the backpressure your present pipes have and not hurt your tune as much.
What is the purpose of the intercylinder baffles?
Purpose and History: Any cooling air that is not forced to contact a cylinder fin as it flows past is wasted energy and wasted cooling. The purpose of the intercylinder baffles is to guide the air, force it to contact the fins, and not allow it to escape unused between the cylinders.
What are the intercylinder baffles on a Continental C-85?
Continental C-85/C-90/O-200 Engine Intercylinder Baffles and Oil Tank Baffle Cessna 120/140/140A Purpose and History: Any cooling air that is not forced to contact a cylinder fin as it flows past is wasted energy and wasted cooling.
How are the deflectors and baffles in an engine?
The pressure differential between the top and the bottom of the engine forces the air past the cylinders through the passages formed by the deflectors. The baffles and deflectors normally are inspected during the regular engine inspection, but they should be checked whenever the cowling is removed for any purpose.
Why are baffles important in liquid cooled engines?
But even tiny leaks in baffles can have huge effects on engine cooling and, therefore, engine longevity as Marc Cook discusses in this month’s Motor Head column. T his will be the column that allows devotees of liquid-cooled engines to rock back in their Aerons, place palms on paunch and proclaim, “Aren’t we the smart ones?!”

How did the hanging baffle get its name?
The original is called the hanging baffle because there is a strip of flexible material hanging from the hinged, opening cowling that fits down across the faces of the rocker boxes to seal the top half of the engine. The entire top area of the cowling is open.
How does a reciprocating engine cool a cylinder?
In each specific case, applicable manufacturer’s instructions should be consulted. Reciprocating engines use some type of intercylinder and cylinder head baffles to force the cooling air into close contact with all parts of the cylinders. Figure 2 shows a baffle and deflector system around a cylinder.
