5. Thrush 17658 Welded Muffler – Best Cost-Effective Upgrade Option
The muffler is made out of stainless steel and features a dual-chamber design. Inside, you’re getting well-designed resonance chambers that can make the best sounds of your engine sing! It’s not as complex as other V6 mufflers as far as baffling goes. But it does the trick.
Even still, this muffler is a worthy option. It gives your engine a bit more room to breathe while turning headache-inducing noise into something more pleasant!
How Do Mufflers Affect a V6 Engine?
Mufflers are a key component that supports your V6 engine. They can do a lot to impact your vehicle’s performance, both negatively and positively. But at its core, a muffler is engineered to do two things: Control sound and control backpressure.
Engines are naturally loud machines. Exact sound levels can vary dramatically based on engine design, chassis, and more. However, the combustion process produces loud bangs, which would radiate through your neighborhood if you didn’t have a solid muffler!
Your muffler dampens the sound, allowing your vehicle to meet state exhaust noise laws.
The second purpose of the muffler is to regulate backpressure. With every firing of a cylinder, your engine generates gases that it needs to get rid of. As a result, the engine creates backpressure to overcome the resistance it experiences from the exhaust system as a whole.
Backpressure is designed into exhaust systems through the muffler, allowing your engine to breathe efficiently while managing the gases it releases into the environment.
Benefits of Upgrading Your Muffler
Now that you understand the importance of your muffler to your V6, why upgrade it? Here are some of the most noteworthy benefits your engine will experience.
Remember that backpressure we went over earlier? Well, an aftermarket muffler can decrease backpressure and help your engine breathe a bit easier.
You see, many stock mufflers are more restrictive than they have to be to exceed environmental regulations. An upgraded muffler can still support the exhaust system to reduce pollutants. But, it will also allow more air to get through to your engine. With more air and less restrictive operation, your V6 can get rid of its gases more efficiently. Thus, it won’t have to work so hard to provide you with better performance!
Some mufflers can provide horsepower gains as much as 10 percent!
Improved Fuel Efficiency
This perk coincides with the previous one. A more efficient engine will use less gas to do the same amount of work! Your V6 won’t have to work so hard to pump out that momentum. As a result, you can save at the fuel pump!
Mufflers are all about reducing noise. But what if you could make the noise more pleasant on the ears?
V6 engines are known for producing a killer growl. Unfortunately, factory mufflers can dampen that deep sound significantly. A new muffler can restore and enhance the sound coming from your engine. They do this by controlling how sound waves move inside. Some mufflers are purpose-built for improving the signature V6 sound!
Choosing the Best Muffler for V6 Engines
While they all look similar, mufflers are pretty complex when you get down to the nitty-gritty.
To ensure that you’re choosing a muffler that complements your V6, pay attention to the following factors when shopping.
There are several types of mufflers out there. Subtle design tweaks can have a big impact on how the muffler impacts the engine.
If you’re looking for sound improvements, chambered mufflers are the way to go. These mufflers have internal baffles and chambers to strategically reflect sound waves. Precise engineering goes into the creation of these mufflers, resulting in noticeable changes in sound quality.
Next up, there’s the straight-through muffler. Also known as Glasspacks, these mufflers are all about performance. They consist of a single straight tube that’s surrounded by insulating material. The insulation absorbs sound without restricting airflow to the engine.
Finally, we have turbo mufflers. Turbo mufflers are like a combination of chambered and straight-through units. They utilize an S-bend. However, the tubes are perforated to let sound waves move into the surrounding insulation. Turbo mufflers tend to offer the most sound reduction. But, they don’t do much in terms of performance enhancement.
Materials and Overall Durability
Mufflers are typically located under the rear of the vehicle. No matter how safe you drive, these components are put through the works! They experience splashes, dings from road debris, and scratches.
When shopping for a muffler, go with a unit that’s built to last. Look for high-quality materials like aluminized or stainless steel. Aluminum and iron alloys work well, too.
Fit and Installation
Of course, don’t forget to take a look at vehicle compatibility. Overall sizing, as well as tube diameters, can vary. The better the fit, the easier the installation process. Take a look at your vehicle’s manual or contact the manufacturer before you buy!
It’s also a good idea to go to a professional if you’re not comfortable with your automotive skills. Some units are DIY friendly, but paying for the skills of a mechanic is never a bad idea.
It’s surprising how much of a difference a new muffler can make when it comes to V6 performance and efficiency. These mufflers complement the function of your engine, providing measurable improvements that can bring out the best in your V6!
We’ve provided many great mufflers to choose from. But, the Flowmaster 953047 Super 40 Series Muffler takes the cake! The chambered muffler has some precise engineering that checks off all the boxes. Not only does it improve airflow to and from your V6 engine, but it treats sound to make driving that much more pleasant. The Delta Flow technology is second to none, making your V6 sound better than it ever has before!
It’s a simple upgrade that can make all the difference. Check it out for yourself and see what you think!
1. Does muffler affect gas mileage?
Mufflers do impact gas mileage. It all comes down to backpressure control and airflow. A well-designed muffler will improve airflow, reducing pressure on the engine. As a result, it can work more efficiently, which will reduce the amount of gas it needs to operate! On average, you can expect a fuel economy jump of two to 10 percent!
2. How hard is it to replace a muffler?
The installation process all depends on the design of the muffler and your vehicle. In most cases, it’s a relatively straightforward process. But, that only applies to mufflers that are the right fit and configuration.
Some units may require more custom fabrication. In those instances, leaving the install to a professional is best.
3. Is an exhaust and muffler the same thing?
A muffler is part of the larger exhaust system. But, they are two different things. The muffler is more focused on controlling sound and airflow. Meanwhile, the exhaust is responsible for controlling the output of exhaust gas. They go hand-in-hand and rely on each other for proper operation.
4. What is the difference between muffler and silencer?
There is no difference between a muffler and a silencer! The term “muffler” is used in America. However, the term “silencer” is used to describe the same part in British English. You’ll often hear people calling it a silencer throughout the United Kingdom and Europe.
