The exhaust system and muffler of your vehicle play a crucial role in its performance, but there are an unfortunate number of myths out there regarding exhausts & mufflers. This article will review a few of the more common rumors about vehicle exhausts & mufflers to help dispel the spread of misinformation and aid drivers with caring for their vehicles.

Myth #1: Louder means more power.

A loud exhaust might sound like it’s doing more for your vehicle, but it doesn’t actually mean that you’re getting better performance. In fact, in some cases, a loud exhaust system actually decreases your power because it interrupts the exhaust flow.

Myth #2: Mufflers are only there for noise control.

While noise reduction is a big part of a muffler, they also help improve exhaust flow and backpressure, both of which can impact the engine performance.

Myth #3: The bigger the exhaust pipe, the better your performance.

An exhaust pipe should always reflect the engine’s needs, and an oversized one can negatively impact backpressure and torque.

Myth #4: Rust on the system is nothing to worry about.

Rust is a problem no matter where it is since it can weaken the system and lead to leaks and other problems, including raising harmful emissions. You should always have a professional address rusting parts as soon as you notice them.

Myth #5: Exhaust tips significantly boost vehicle performance.

The truth is that exhaust tips are almost entirely cosmetic and have very little impact on a vehicle’s performance. Different exhaust tip designs can have a major impact on a vehicle’s sound, but it’s not going to impact the engine or impact performance in any major way.

If you have additional questions about exhausts & mufflers, it’s always best to seek the advice of a skilled professional who can talk you through your concerns and provide an accurate, dependable answer.
