What is the theory of motorcycle exhaust design? What is the purpose of the motorcycle exhaust? Does 2 into 1 exhaust make a difference How do I quiet a motorcycle exhaust? Or, How do I reduce my exhaust noise? Can exhaust increase speed? How much HP does exhaust add? Will dual exhaust increase horsepower? How to get a deeper exhaust sound? Does exhaust affect performance on a motorcycle? This content is all about the motorcycle exhaust function, purpose, and other details.
What is the Use of Exhaust in Bike?
An exhaust is a crucial part of the motorcycle. It actually removes the unnecessary waste gasses from the engine. During the combustion process, some by-products get generated which don’t actually have any function to do. Those gases are hot and toxic. Thus the exhaust throws those harmful by-products or gases out in a systematic way. The exhausts of the modern-day bikes do more than those tasks. They don’t only work to reduce emissions but also regulate the sound the engine makes during the process.
How Does Motorcycle Exhaust Work?
The exhaust gases move their way out of the cylinder at the speed of the sound. Those gases then enter into the header pipes. In the next phase, gases move towards the wider parts of the exhaust where they get expanded. In the process, it creates backpressure that indeed travels back towards the engine. The pressure difference naturalizes better efficiency.
In the old models of bikes, the exhaust used to be like a little more than a pipe. It is used to exhaust away gases from the engine into the atmosphere. The ‘straight pipe’ exhaust actually had no cross-sectional changes in its design. With the decreased effort required to push exhaust gases, there was higher power output in the alluded model. But it would cause worse mileage and fuel consumption.
But the exhausts of the most modern bikes do feature catalytic converter. It converts the highly toxic and pollutant exhaust gases into less harmful gases. As they are converted into less harmful conditions before being exiled to the atmosphere, the controlled emission is more environmentally friendly.
The likes of platinum, rhodium, palladium, etc are the elements of the catalytic converter. There are 2 stages of reaction between the exhaust gases as well as the catalysts. In the initial stage, the harmful nitrogen oxides are converted into less pollutant nitrogen and oxygen. The latter mentioned is a useful gas and moves out while the catalytic converter captures Nitrogen. In the 2nd and last stage, the likes of hydrocarbons, carbon monoxide, and other harmful gasses are assessed.
The exhaust system’s muffler is the other component. The shape and size of the muffler along with various internal components determined the loudness of the system’s sound.
What makes a Motorcycle Exhaust Loud?
The exhaust systems of a bike are quite loud. But actually why the bike exhausts are loud? Here we will find out the reasons.
- The small size of the exhaust system is one of the main reasons. There isn’t enough space to fit the additional components to lessen the sound.
- Muffler which is an acoustic device used to minimize the engine sound. The size of the muffler is also small which is another reason.
- A fully exposed motorcycle engine is open to the atmosphere and hence also makes sheer noise.
How to Reduce Exhaust Sound in a Bike?
How do I make my exhaust not loud? Well, you can lessen the excessive noise made by your bike’s exhaust.
- Check for holes and if there are any, seal those.
- Wrapping up the pipe will definitely be a handy solution to minimize the exhaust’s sound.
- For sudden and excessive noise, you might be required to change the muffler.
- Fitting the exhaust silencer will be a good option to remedy the noise.
- If you are facing many issues and it seems almost impossible to get rid of the sound, you must change the pipe.
Does an Exhaust make a Motorcycle Faster?
You will be surprised to know that an upgrade of the exhaust system can actually make your bike faster! How? When you upgrade the exhaust system it may help acquire a better horsepower and torque. You know, with more horsepower your bike will click higher top speed and better torque will help have good acceleration. Does exhaust add horsepower to a motorcycle? Proper installation of a full exhaust system may help your bike acquire an increase in horsepower from 5 to 15 HP.
Is Single Exhaust Better than Duals?
In the dual-side system for exhaust pipes, there will be a couple of pipes adjacent to each other. In the single exit pipe, there is only one. Actually, the dual exhaust system is more efficient in expelling the exhaust gases. It is able to ensure better performance. The benefits provided by the dual exit exhaust system include:
- Better mileage and fuel efficiency
- Reduced engine temperature
- Increased horsepower of the engine
- Deeper sound of the exhaust
However, there are some drawbacks of the dual exhaust pipes including deeper exhaust sound itself along with a shorter lifespan.
What’s Better, Dual Exhaust or Single Exhaust?
As it is able to remove the gases more efficiently and lets the engine breathe more comfortably, the dual exhaust system is better. It also helps gain increased horsepower, torque, and fuel efficiency.
Does Exhaust Affect Bike Performance?
A good exhaust helps having the optimal performance of the engine and also keeps the engine health good. Meanwhile, a cheap exhaust can cause serious damage to your bike and will also affect the performance of the engine.
