Racing mufflers are becoming a trend in the automotive world. In addition to their sporty appearance, their powerful sound tempts many people to replace their standard mufflers. But, does using a racing muffler increase the performance of a motorbike or just make it noisy? Let's discuss the facts and myths on otomodify
Racing mufflers increase speed?
Fact. Racing mufflers are designed to make gas run smoother. The shape of the racing muffler can help the process of removing combustion residue faster, thereby speeding up the engine cycle and increasing performance. However, this increase in performance will be much more effective or felt if accompanied by other adjustments such as ECU remapping or changes in the carburetor or injection sector.
The noisier the faster?
Myth. Even though a motorbike uses a louder racing muffler, it will not have any effect on the motorbike's performance. This is often misunderstood by some lay people. Thinking that the louder the exhaust sound means the faster the performance of a motorbike. On the other hand, using a fake racing exhaust that only relies on loud noise can reduce the performance of the motorbike.
Direct effect on acceleration
Fact. It can be yes or no. This depends on the overall settings of a motorbike. It also affects the type of motorbike. The right racing exhaust can make acceleration more responsive, especially at high RPM. On the other hand, if a racing exhaust is installed on a standard motorbike without resetting, the result can actually be flat. The pull becomes heavier and power is lost at low revs.
Resetting is mandatory
Fact. This is one of the most important things. Especially if the motorbike used is a motorbike that should not use a racing exhaust. Without doing a complete reset, the motorbike can actually have many problems. Modern motorbikes that already use injection should have their ECU remap if they want to use a racing exhaust. For carburetor motorbikes, changing the size of the nozzle or pilot jet can be a solution. Without this, the mixture of fuel and air can be chaotic. As a result, the motorbike is more wasteful, reckless, or even damages the engine in the long term.
Psychological effects on riders
Many motorcyclists replace their exhausts with racing exhausts not only to improve motorcycle performance but also to increase self-confidence. Some people even feel that their motorbikes are faster if they use racing exhausts even though they are actually only loud in the sound. In fact, what actually happens is nothing more than an illusion. But from a mental perspective, this placebo effect is big enough to make riders feel more powerful.
Exhaust price does not determine quality
Fact. Many racing exhausts have exorbitant prices because they have a loud appearance and sound. However, this does not guarantee that the racing exhaust fits or is appropriate. But there are also racing exhausts that are sold at low prices and have a simple design but are suitable and in accordance with engine specifications. So the point of the statement above is to choose a racing exhaust that matches the engine specifications of the motorbike that will be installed.
What is it suitable for?
Racing exhausts are suitable for motorbikes with modified setups. If the motorbike is still standard, you should think twice about replacing the exhaust. Racing exhausts are most suitable for:
- Racing motorbikes
- Contest motorbikes
- Motorcycles that have been upgraded in terms of engine and fogging
Racing exhausts for daily use
Racing exhausts are actually not recommended for daily use. The loud sound can disturb the surrounding environment. However, if you still want a racing exhaust for your motorbike, use a DB Killer. Choose a semi-racing model with a removable DB Killer.
Don't forget driving ethics
In its use, racing exhausts have different sound thresholds in each country. This regulation is certainly made so that all drivers remain safe and comfortable while driving. The use of DB Killer is highly recommended if you are in a crowded environment. Speeding with a racing exhaust in a narrow alley or in front of a neighbor's house? Big no. Racing exhausts are not a reason to disturb the comfort of others. Respect public spaces, and use motorbike sound wisely.
Conclusion
From the facts and myths above, do you still want to use a racing exhaust? If so, make sure to remain ethical while driving.
