Exhaust systems 

Exhaust systems for motorcycles, scooters and ATVs play a key role in vehicle performance and sound. The exhaust system is responsible for directing and controlling the flow of exhaust gases from the engine to the rear of the vehicle. There are several types of exhaust systems used on motorcycles, scooters and ATVs.

One popular type is the slip-on exhaust, which is relatively easy to install and offers a noticeable increase in power and torque. A full exhaust system is another option that replaces the entire factory exhaust system and provides an even greater increase in performance, but is more complicated to install.

Another type of exhaust system is the performance exhaust. This type of exhaust is designed to increase the horsepower and torque of the engine by allowing exhaust gases to flow more efficiently. Performance exhausts can be made of different materials such as stainless steel, titanium, and carbon fiber, that also affect the weight of the system and the overall sound of the exhaust.

In addition, many exhaust systems are equipped with a catalytic converter to help reduce emissions and meet standards set by environmental agencies.

Overall, exhaust systems are a great way to improve the performance and sound of a motorcycle, scooter or ATV, and there are many options available to suit different needs and preferences.

Does an aftermarket exhaust improve performance?

Yes, an aftermarket exhaust can improve performance by increasing exhaust flow and reducing backpressure. This can result in an increase in power and torque. However, the exact improvement depends on the specific motorcycle and exhaust system. It is important to note that installing an aftermarket exhaust can also negatively affect performance if it is not properly designed or installed.

Do I need to remap my motorcycle's ECU after installing a new exhaust?

It depends. Installing an aftermarket exhaust can affect the air/fuel ratio and engine performance, so a remap of the engine control unit (ECU) may be necessary to ensure optimal performance and prevent potential engine damage. The need for a remap will vary depending on the specific motorcycle and exhaust system, so it's best to consult a professional mechanic or exhaust system manufacturer for guidance.

Will an aftermarket exhaust void my motorcycle's warranty?

It depends on the specific motorcycle and the terms of the warranty. In some cases, installing an aftermarket exhaust may void the warranty on the engine and related components, but not the overall motorcycle warranty. It is best to consult the motorcycle manufacturer and review the warranty terms before installing an aftermarket exhaust.

What is the lambda probe on a motorcycle used for?

"Lambda probe" or "O2 probe", the oxygen probe ensures the ideal composition of the fuel-air mixture, for maximum efficiency, minimum fuel consumption and optimal conditions for the catalytic converter. More efficient combustion not only minimizes damage to the environment by reducing emissions, but also helps reduce the cost of operating a vehicle, both by saving money on fuel and by wearing the engine less.

The sensor detects the amount of oxygen in the exhaust gas, and its electronic signal is used by the engine control unit, which changes the amount of fuel injected accordingly. The working principle of the sensor is its ability to transmit oxygen ions. If the oxygen content on the active surfaces of the sensor (one in contact with the atmosphere and the other with the exhaust gas) differs significantly, the voltage at the terminals of the sensor changes dramatically. Nowadays, two oxygen sensors are often installed: one before and one after the catalytic converter.

How many decibels are allowed for a motorcycle in europe?

The specific decibel (dB) limit for motorcycles in Europe can vary depending on the country or region. However, in general, most European countries have a maximum noise level limit of around 80-82 dB for motorcycles.

For example, in the European Union, the noise limit for motorcycles is 80 dB for all motorcycles and mopeds registered after July 1, 2016 and this applies to all new type-approved models.

It's important to note that some countries also have different limits for different types of motorcycles, such as sportbikes, cruisers, and touring bikes. Additionally, some countries may have different limits for motorcycles with different engine sizes. Therefore, it's always recommended to check the specific regulations for the country or region where the motorcycle will be used.

It's also important to note that in Europe, the measurement of noise emission is done under specific conditions and test procedures, the so-called "Drive-By" test, which measure the noise level at a specific distance from the motorcycle while driving at a specific speed.
