Before considering what might make for the best muffler for your truck or SUV, it’s important to understand what this component is, and what it does.
Like the name suggests, a muffler is a device used to muffle or lessen the sound emitted by an automobile’s internal combustion and exhaust systems.
Globally, the automotive muffler market reached 10,166.2 USD in 2022 at a CAGR of 6.2%. So, needless to say this is a hot commodity, and that there are a wide range of options available to you.
But, depending on your model and personal preferences, the following tips and tricks can help ensure that you make the right purchase, instead of dropping your dough on something that’s completely worthless!
Since the muffler will be used to lessen the noise your vehicle produces from its tailpipe, you must first understand what kind of exhaust you have.
A single exhaust system requires only one inlet on the muffler, while a dual setup requires two. If you’re planning to merge a dual-exhaust system into a single muffler you’ll still have to purchase a dual-inlet muffler.
The next thing to take into account is the diameter of the exhaust pipe itself. The muffler should match both the inlet and the outlet diameters to fit snugly.
If you’re unsure what diameter your exhaust pipe is, you can look up the best performance mufflers online and match the results with your vehicle.
You have to ensure that the outer dimensions of the muffler can accommodate proper clearance underneath the vehicle.
With the muffler of the right dimensions, you can install and bolt the components easily into place. The muffler should fit comfortably within the vehicle’s casing underneath so that it doesn’t get dislodged from the undercarriage.
Performance mufflers can reduce the backpressure emitted by the exhaust system in various ways. Some mufflers can remove all kinds of restrictions that may arise in the exhaust path, such as diffusers or backflow that hinder flow.
While this is a good type of muffler design, it often doesn’t drown out noise very well, which defeats its basic purpose.
On the other hand, a performance muffler that drowns out most of the noise can’t handle backflow pressure.
Mufflers must withstand high pressure, which means that they need to be built from strong materials like steel or titanium. They also need to be able to absorb impacts from the road. Most manufacturers typically use a three-layer body with a hard outer layer, an inner case, and an insulated layer between these two.
While titanium exhausts are the lightest and strongest, they are also extremely expensive. Stainless steel mufflers offer much equal amounts of performance gains, and have an impressive lifespan if produced from good materials.
There are three common types of muffler designs that you can pick according to your vehicle design and needs.
This system is ideal for muscle cars and street machines. They considerably reduce noise and produce a throaty sound.
Here, a set of perforated tubes guide the exhaust fumes outward quickly, making this style ideal for forced induction applications that do not appreciate back pressure.
Zero impedances, with very little muffling material for maximum flow, power, and noise.
Speaking of noise, before you decide on a muffler, it’s always a good idea to research the noise rules and regulations in your locality and the places where you’re planning to drive your truck or SUV.
For example, if you already have a stock muffler and replace it with an aftermarket automotive muffler, you might end up with high levels of noise that might not meet local guidelines.
Most states and countries have a maximum limit for automotive exhaust systems, so ask the seller before proceeding.
