The exhaust system is a very important part of the motorcycle, which has 3 main functions: it routers the combustion gases away from the rider, they muffle the noise and they improve the performance of the engine. Despite its proven importance, few riders put a lot of effort into getting the best exhaust for their ride. Today, we are going to dig a little deeper into this matter, and see whether or not you should replace your current exhaust pipe.
Are factory systems bad?
We can’t tell you for sure if your factory exhaust is good or not, because this depends on each individual bike. There are some motorcycles out there that come with terrific exhausts, but this is not the case for all of them. In fact, most of them have mediocre systems and this is to be expected, because the original equipment manufacturers have to stick to certain budgets. This means that they sometimes have to make compromises, and these compromises must be made in areas that the customers are not that familiar with. If you make compromises in terms of design or power, this is something that customers are bound to observe, so you compromise in less popular areas such as the exhaust system. On the other hand, many aftermarket manufacturers produce exhaust components with racing experience in mind, so power gain is their main purpose. We recommend M4 Exhaust, which is one of the best exhaust system manufacturers of the moment. They offer a M4 offers a wide variety of choices from high-mount, to street slayer or race styles, and you can choose between full and slip-on systems.
Benefits of replacing the factory exhaust
- Power – As we already mentioned, a higher quality exhaust system will improve the engine performance, which means more power. This happens due to the fact that a better exhaust system will help the engine expel the exhaust gases easier. This way, the engine will waste less energy on the pumping out the exhaust gases, and the extra energy will be distributed to pumping more power.
- Lose some weight – If your bike came with a bulky dual exhaust system made of steel or another heavy material, replacing it with single muffler titanium unit can help you significantly reduce the weight of your motorcycle. You can shed anywhere between 10 and 18 pounds, depending on the the weight of the factory system and the weight of the aftermarket system.
- Change your bike’s purr – The way that a motorcycle sounds can significantly change the riding experience. There’s nothing more disappointing than a bike that looks like a dragon but sounds like a tamed kitty. So if you want your bike to not only look good, but also sound like a beast, you should definitely consider an aftermarket exhaust.
How to choose a quality exhaust system
If you don’t have the budget to replace the overall exhaust system, you can start with a muffler upgrade. It is cheap, it will give you a small power increase and a small weight shed, and it will also include a spark arrestor. When it comes to a full system, there are a few factors that you should consider. For best results, choose a titanium system with carbon fiber elements, as these are the most lightweight materials. Keep in mind that if you replace the overall system, you will have to adjust your fuel mapping by installing a fuel controller. Last but not least, remember to choose a reliable manufacturer, such as M4 Exhaust, which designs some of the highest quality exhaust systems of the moment.
