Do Mufflers Increase Horsepower?

Many questions have answers that are debatable—why did the chicken cross the road? What came first, the chicken or the egg? And, how many blondes does it take to change a lightbulb? But, when it comes to the question “do mufflers increase horsepower?” There is only one right answer—yes. Ditching your inferior stock muffler and upgrading you ride with a high-quality performance muffler can give you major boosts in power and performance. Here’s how:

How Do Mufflers Work?

Air resistance or backpressure makes it hard for exhaust fumes to exit a cylinder, and it robs your engine of potential power. When an exhaust pipe is too small or a muffler has a lot of air resistance, this can cause nasty backpressure. So, when you upgrade your muffler or your entire exhaust system to one with larger pipes, you can eliminate this backpressure, therefore allowing air to exit more easily, and giving your ride a big boost in power.

When upgrading your muffler and increasing horsepower, you want to stick with the brand names you can trust. Flowmaster exhaust systems and Magnaflow mufflers, for instance, are known for delivering massive boosts in power and performance. Also, you want to choose a muffler or exhaust system based on the needs of your specific vehicle. For example, do you need a diesel exhaust for your heavy hauler? Or, how about a dual exhaust for your sporty street machine?

Finding the Best Muffler for Your Ride

Not all mufflers are designed the to produce the same results. So, depending on which muffler you choose, you may have a deep, throaty growl, or a softer, clean rumble. If you’re looking for a muffler that delivers maximum power with minimum resonance, look no further than the Magnaflow XL Turbo Muffler. Or, for one of the most aggressive, deepest-sounding performance mufflers on the market, choose the Flowmaster Super 44 Muffler.
