Loud mufflers are a type of vehicle exhaust system that is designed to make a loud, booming noise. This is done by adding a perforated pipe to the exhaust system that amplifies the engine’s sound. Loud mufflers are popular among car and motorcycle enthusiasts who want to show off their powerful engines.
However, they can be extremely loud and annoying to others, which is why many cities have laws against them. If you’re considering installing a loud muffler on your vehicle, make sure you understand the local laws first.
While loud mufflers are not legal in most states, most people fancy them. In this guide, I will be looking at some of the loudest mufflers you can get on the market today.
What Is the Loudest Flowmaster Muffler?
Flowmaster mufflers are renowned as the benchmark for regulating your vehicle’s engine noise.
Flowmaster categorizes its mufflers into three distinct sound levels: Aggressive, Moderate, and Mild.
In the Aggressive category, these mufflers produce the most pronounced and attention-grabbing exterior exhaust sound, accompanied by a noticeable increase in interior sound and vibration. While some of these mufflers are street-legal, they often fall into the realm of racing-level exhaust systems.
Moving to the Moderate category, which is particularly popular among truck owners and those with V6 or V8 engines, you can expect a balanced mix of exterior sound that’s noticeable but not overwhelming, coupled with minimal interior noise and vibration.
Finally, in the Mild category, drivers can enjoy lower sound levels that closely resemble the stock or factory exhaust volumes while adding a touch of unique tonal character to their vehicle’s exhaust note.
