The muffler features Borla’s XR-1 Raceline technology. This technology is all about creating uninterrupted flow. There are no baffles or complex chambers. Instead, you’re getting an ultra-wide muffler where exhaust gas can flow freely.
Overall, the muffler is a good choice if performance and fuel efficiency are your top priority. Depending on your truck, you can experience significant improvements to your average MPG rating.
4. Cherry Bomb 87522 Glasspack Muffler – Best for Install Flexibility
Cherry Bomb is a favorite among V8 owners looking for enhanced performance and a loud growl.
Cherry Bomb 87522 is a muffler that you get when you want your engine to roar! It’ll bring the best out of your V8 in terms of performance, too.
5. Magnaflow Performance Exhaust – Best for Sound Enhancements
However, the component’s length manipulates the engine noise just enough to produce a smooth, deep growl. Not only that, but it does a decent job of dampening the noise, too.
This muffler provides a noticeably different sound than stock units. Thanks to the added length and sound absorption, the tone you’ll hear will remind you of the power of your V8 without going overboard.
Why Upgrade Your V8 Muffler?
All vehicles come with a muffler from the factory. This component plays a crucial role in dampening engine noise and controlling emissions. You can’t go without a muffler! So, why upgrade to an aftermarket one?
Many V8 truck or car owners choose to upgrade their muffler to take full advantage of the engine. You see, stock mufflers help manufacturers achieve very specific goals. Factory trucks must appeal to the masses, so manufacturers have to find the right balance between noise reduction and power.
Aftermarket mufflers often improve laminar flow. In most cases, this is because of wider pipes. The level of backpressure on the engine manifold decreases. As a result, your V8 engine is able to breathe easier and produce a bit more horsepower.
Better Fuel Economy
Believe it or not, an aftermarket muffler may provide improvements on your fuel efficiency, too. When your engine breathes better, it’s not working so hard to push exhaust gas out of the piping. With less work, the engine can use fuel more efficiently. It’s a win-win all around!
Did you know that many jurisdictions have laws about muffler noise? You’ve probably heard horror stories about truck owners getting fined because of how loud their engine is roaring.
Most states have some kind of law in place that prohibits “excessive or unusual” noise levels. If you live in one of these areas, upgrading your muffler to a quieter one may be beneficial to you in the long run.
That growl you hear when you’re cruising along the highway is nothing more than pulses of high and low pressure. V8s already have a great reputation for producing a soothing growl. But maybe you’re looking to enhance that sound even further. If so, a new muffler will do the trick.
Mufflers have a significant impact on engine noise. Every detail from material to design will change the characteristics of the sound. It’s not uncommon for truck owners to make upgrades just because they want to enhance that signature growl.
Different Types of V8 Mufflers Available
There are three main types of mufflers for V8 vehicles. They vary widely in design and can produce different results.
A straight-through muffler is relatively simple in design. It’s based on the classic muffler design and usually incorporates a straight pipe. As the name would suggest, exhaust passes through the pipe.
They work on the concept of absorption. As the sound waves pass through, the material inside the pipe absorbs the sound. Usually, it’s a form of fiberglass. That’s why you’ll often see these mufflers being called glasspacks.
Chambered mufflers are a good option if you’re looking to enhance the tone of the engine noise. These mufflers are usually wider. That’s because they contain a series of chambers and baffles.
Exhaust gas travels through these chambers to achieve a specific tone. Manufacturers will go to great lengths to produce a certain sound, so these components are finely tuned to V8 engines!
Finally, there are turbo mufflers. You can think of these as a combination of straight-through and chambered mufflers. Typically, they have a long S-shaped pipe with several perforations to manipulate exhaust gas accordingly.
Interestingly enough, turbo mufflers are the quietest and most restrictive. They aren’t great if you’re trying to improve performance. But, they can make your engine super quiet.
Before you start shopping for a new muffler, there are a few things to consider.
These components play an integral role in your truck’s performance. They can also impact the riding experience, so this isn’t a decision you should take likely.
To ensure you’re getting the right muffler for your needs, keep the following factors in mind.
Your muffler will go through the wringer! Even if you stick to on-road driving, it’ll have to withstand debris, heat, and tons of pressure. You need to choose a muffler that’s built to last.
Look for high-quality materials like stainless steel, aluminized steel, or aluminum alloy. Most mufflers these days are made of some type of iron alloy. But, you can easily pay more for something stronger.
Impact on Performance
A new muffler will directly impact performance. As we said earlier, many aftermarket units will improve fuel efficiency and horsepower capabilities. But, that’s not always the case.
Scrutinize the design and do some research before you commit to a muffler. Generally, those designed for noise reduction are going to harm performance. But, those that free your engine up to work harder may be on the louder side. You have to decide which feature is most important to you and find a muffler with the right balance.
Fit and Compatibility
Finally, you need to make sure your new muffler fits! This should be the first thing you look into. Mufflers come in a wide range of sizes and shapes. Not all of them are going to fit on your V8 vehicle.
Pay close attention to compatibility. If you’re not sure about what works for your truck, do a bit of research. You can contact your manufacturer or speak to an installer to find units that work for your vehicle.
1. What is the purpose of a car muffler?
The main job of a muffler is to reduce loud sounds coming from the engine. Your V8 produces a lot of burnt gases during the combustion cycle. When the gases release into the exhaust system, they create some powerful sound waves. The muffler works to soften the sound waves so that your engine stays relatively quiet.
2. Is it safe to drive a car with a broken muffler?
This all depends on how it’s broken. Sometimes, cracks and holes in mufflers can release carbon monoxide into your car. Continued exposure to that carbon monoxide can lead to several symptoms. In severe cases, carbon monoxide can even lead to death!
3. Does muffler make the car faster?
Some mufflers can improve your engine’s performance, which will allow you to reach faster speeds. Stock mufflers tend to create a lot of backpressure, which slows the engine down a bit. With a good aftermarket muffler, the engine is able to get rid of exhaust gases more efficiently, which results in more power.
4. How long does it take to replace a muffler?
Typically, replacements can take anywhere between two or three hours. But that’s only if you know what you’re doing. If you’re new to automotive work, it may take longer. Seasoned professionals may also get the job done quicker. However, that all depends on any additional work that might be required to install your muffler.
There’s no better way to improve your V8 car than a new aftermarket muffler. Standard stock mufflers get the job done. But an upgraded muffler will let your engine sing!
You have a lot of great mufflers to choose from. However, we recommend going with the Flowmaster 953047 Super 40 Series. It checks off all the boxes and can do a lot to enhance your ride.
Not only does it improve resonance to produce that killer engine tone you’re after, but it can also enhance performance. The Delta Flow technology inside the muffler is second-to-none and helps your engine reach its full potential.
But don’t take our word for it. Try it out and see for yourself!
