SUPER QUIET 3 INCH MUFFLER HOW TO
How to Find the Quietest Performance Muffler You’ll just have to find the best performance muffler for your vehicle. So ultimately, the answer to the question of whether a muffler can make your exhaust quieter without affecting its performance is a resounding yes. Still, many manufacturers have taken to making hybrids of these two styles, featuring fewer baffles and more sound-absorbing materials. That makes them more efficient than silencers that merely absorb some of those soundwaves.
While some use perforated tubes, others rely on resonating chambers to decrease the sound pressure of certain frequencies.Įssentially, these kinds of mufflers use reflected amplitude pressure waves that are 180 degrees out of phase to cancel out the sound waves coming from the engine. These silencers use destructive interference to control sound thanks to the internal shape of the structure. In any case, reactive - or, rather, reflective - mufflers are generally considered to be more effective. These are typically straight-through mufflers with a perforated tube in the middle that is surrounded by different kinds of insulation. On the one hand, you have absorptive or dissipative mufflers, which use insulation to absorb the sound pressure of the engine noise. The way that happens depends on the type of muffler you go for. Because of that, most people use resonators and mufflers together, though some mufflers can perform both tasks by effectively reducing noise across the board. Still, resonators can only eliminate the headache-inducing frequencies that usually bother people, thereby creating a richer exhaust sound. In a way, some mufflers are similar to resonators, which take the bite out of exhaust noise by flattening the sound of the exhaust noise. But is that even possible? Can we expect such a drastic change from a 20 or 30-inch long tube? In theory, a performance muffler should reduce exhaust noise without affecting your vehicle’s functioning. Still, achieving that effect is not as simple as you’d think! Can a Performance Muffler Make Your Car Quieter? That’s how a piece of metal can reduce noise while enhancing fuel economy and improving the horsepower of a vehicle. Rather than stopping the gas from going out, a performance muffler might make its path more complicated by pushing it through tubes and around baffles. Yet to have a true performance muffler, the piece also needs to have next to no effect on airflow. So installing a muffler is also a way to expand that network, adding length and distortion. The longer those pipes are, the more chances the sound has to lose energy and dissipate. Now, depending on the size of the vehicle, an exhaust system can be anywhere between 8 and 16 feet long. Ultimately, the pipes act as a trumpet, amplifying the noise coming from the engine. In the end, the gaseous blasts exit the exhaust at 80–100 psi, on a wave of thunderous noise. The chemical reactions that happen in that chamber are often accompanied by fairly explosive sounds as well. To understand how it works, we have to start by examining the exhaust system itself.Īs you can imagine, the purpose of the exhaust is to expel the gases that come from the combustion chamber of the engine. Conversely, a muffler that’s designed with performance in mind should prevent that from happening. But as we have previously established, regular mufflers can negatively affect the performance of a car to the point of reducing its horsepower. The main purpose of a muffler is to silence the noise coming from the exhaust pipe of a vehicle. What Is the Purpose of a Performance Muffler?
