The exhaust, essential for the proper functioning of your 50cc motorcycle, guarantees optimal performance while respecting environmental standards. It is one of the most important parts of your machine. Indeed, it allows both to improve its performance but also to give it a particular look.

What is it ?

The muffler is a component of the exhaust system of a motor vehicle. Its main function is to evacuate burnt gases and vapors generated par the engine as far as possible from the intake, while reducing their harmful effects on the environment. It also helps reduce the noise generated par the engine and improves the performance of the machine.

It consists of several parts:

• The expansion pot: it collects the burnt gases to expand them in order to cool them and stabilize the pressure.

• The catalyst: it is used to reduce pollutant emissions caused byar the exhaust by filtering them. It is necessary to have road approval.

• The silencer: as its name suggests, it helps reduce the noise caused byar engine. Here again, the presence of the silencer is essential to avoid being fined for excessive noise.

Its operation

The exhaust collects burnt gases from engine combustion. These gases are then cooled and their pressure is lowered in the expansion pot, then are filtered par the catalyst before being evacuated to the outside via the silencer.

It is important that the exhaust matches the cylinders of your vehicle. If this is not the case, the engine may consume more and make more noise or, conversely, lack power.

The importance of approval

To be used on public roads, exhaust pipes must meet certain standards, particularly in terms of noise level and reduction of polluting emissions. However, you can use a non-approved model if you do track racing or off-road competitions.

How to choose your exhaust for a 50cc motorcycle

Compatibility

The exhaust you choose must be suitable for your vehicle. The make, model, engine type and cylinder capacity of your two-wheeler or quad determine the type of exhaust that is compatible.

The material

The material of the pot influences its weight, corrosion resistance and lifespan. They can be made of steel, stainless steel, titanium, or carbon. Each material has its advantages and disadvantages.

• Steel: Strong and more economical but heavier. It is also the material that deteriorates the fastest.

• Stainless steel: the most economical solution if you are looking for an exhaust that will last over time. Stainless steel is a variant of steel, more resistant to corrosion.

• Carbon: lighter and more aesthetic but more expensive and degrades more easily due to heat.

• Titanium: 40% lighter than steel and stronger than carbon but more expensive and conducts heat better (beware of burns!).

Impact on the performance of your 50cc motorcycle

Changing the exhaust can have an impact on the performance of your vehicle, whether in terms of weight, engine power or simply the sound produced.ar the vehicle.

Vehicle use

50cc motorcycles can be equipped with high-pass or low-pass exhausts. The choice depends on the use you have for your vehicle, so you must take into account the use you have for your 50cc before choosing an exhaust.

High passage pot

The high passage muffler is recommended for off-road mécaboîte models, cross, enduro. Indeed, due to their position in the motorcycle, they are protected from impacts in the event of a fall and from stones. Plus, it offers a bit more acceleration than the low shift.

Low passage pot

The low passage exhaust is preferred for road travel only.ar more exposed to shocks, being placed under the motorcycle. It offers better performance at high revs.

It should also be noted that some exhausts are approved for competition only while others are approved for road use, so keep this in mind when making your choice.

Maintenance and repair

Maintenance actions

The exhaust requires regular maintenance. For this, a deep cleaning is recommended. This helps remove residue and soot that can affect the proper functioning of your vehicle. Regular checking of the condition of the exhaust is also necessary.

Signs of a faulty exhaust

When an exhaust shows signs of wear or damage, it is generally recommended to replace it. Some of the most common signs include a decrease in vehicle performance, abnormal noise, increased fuel consumption, or unusual coloring of the pot.

How to change it

Replacing an exhaust pipe involves several steps: dismantling the old pipe, installing the new one and carrying out safety checks. It is recommended to entrust this operation to a professional to avoid any risk.
