The main feature of this hardware is its reversible design. The material is crafted from rust protected stainless steel. It will provide you great reliability and endurance even if you drive on rough conditions.

You will get good protection against rust and other kinds of corrosion. This is a big deal for an exhaust muffler. Because mufflers are more prone to wearing off because of it’s exposed placement under the vehicle.

The chamber is oval-shaped. It weighs roughly around 9 pounds. The manufacturer designed the inlet and outlet of 3 inches diameter. But you should always mention your vehicle model while buying for the perfect fit. Otherwise, you need to DIY some welding jobs to make it work.

But you can push it harder if you want a more growling sound to piss your neighbors off. In fact, at this price point, there is not anything to complain about. You will not surely get better performance than the pricier alternatives. But this is a great contender and it provides an excellent value undoubtedly.

This is yet another muffler from Flowmaster. Flowmaster itself is a brand and it needs no exaggeration. The style of this muffler is a bit different than the conventional mufflers. It has a single inlet pipe and dual outlets. If you want the best muffler to make V6 sound like V8 then this is the one to go for.

This product falls in their Super 10 lineup of mufflers. The Super 10 series is intended for extra loud sounds. This is why it is most likely for use in off-road driving. Your sporty SUV or truck will just roar with this muffler.

The muffler has a large chamber. The overall footprint is huge. There are some extension tubes attached to this muffler. This is why you can install this muffler in most cases without any additional weldings or tubes.

The weight of this muffler is more than 20 pounds and this is quite normal for this exceptionally large muffler. The build quality is superb. I don’t think anyone will have any complaints regarding this. The stainless steel material used in this muffler is way better than aluminized material. This can prevent rust and corrosion at ease.

Although this is smaller than their Quiet-Flow series of mufflers, it is not that lightweight. But I think the 16 pounds weight will not add up much to the vehicle weight. The weight is mostly because of the stainless steel used in this muffler.

But that doesn’t mean the cheap mufflers are not good for your vehicle. All you have to do is prioritize your demands. Some mufflers will produce loud noise while some will remain quiet. Again some mufflers will have advanced tech that will boost up the vehicle performance.

You should know all the aspects of a good muffler and what kind of muffler your car needs. Thus you can choose the best muffler for v6 engines that will last longer and sounds great. Here I am discussing some important aspects that you should consider before buying your first custom muffler.

Build Material

This is the most important factor of an exhaust muffler. The material is everything. It also affects other aspects of a muffler. Most of the mufflers are made of either stainless steel or aluminized iron. Stainless steel has better temperature resistance. Also, it can withstand corrosion and rusts.

Some mufflers have a coating on top of metal sheets. Painting coats are great for protecting your muffler from extreme weather conditions. However, it may affect the sound waves produced by the muffler. This is why you should be careful about the build material.

Welding

The muffler is not a unibody structure. Rather it has joints and connections with inlet and outlet pipes. These have weldings on it. There are different types of welding methods. Metal Inert Gas or MIG welding is a common technique. It is also good for durability and strength.

Although you don’t need to know the details about the welding techniques they used. But always check out the finishing and welding joints. If they seem sturdy then you are good to go.

Dimensions

There are different types of components in an exhaust muffler. They have different dimensions. The chamber dimension plays a great role in the overall performance and sound notes. On the other hand, the inlet and outlet pipe diameter are very important to install it in your vehicles.

Sometimes you can tweak the dimensions by trimming and adding extra metal sheets, to do the job you can use trim removal tool. But it’s always good to go with the perfect dimensions intended for your vehicle model.

Sounds Notes

Most people change their vehicle mufflers for modifying the sound notes it produces. The young generation prefers growling and aggressive sound effects. While the cops may not tolerate the extra aggressiveness of the muffler. However, loud noise is okay for off-roading and racing.

Different people have different sound tastes. So, choose your muffler wisely. You can watch some YouTube videos to hear the exact sound of a particular muffler. Thus you can be more confident while making a purchase decision.

Performance

Normally the mufflers reduce the performance of a vehicle. But nowadays the mufflers are becoming improved. They are using such technologies to create a smooth flow of the exhaust gas. Even some mufflers will significantly boost the vehicle torque and overall performance. Some mufflers are built exclusively for the racers who want better sound without any drop of performance.

Frequently Asked Questions

What does an exhaust muffler do?

The exhaust muffler works like a silencer used in the guns. When the exhaust gas releases through the exhaust pipe, it creates a loud noise. This is because of the strong thrust of burnt gases. The chamber of the exhaust muffler minimized the loud noise. Sometimes you can maximize the noise based on your taste by using a modified exhaust muffler.

What is the difference between silencer and muffler?

The silencer is used in pistols or rifles. It almost kills the noise of the exhaust gas while shooting a bullet. On the other hand, the word muffler is used instead of a silencer in the automotive industry. This is a US English term. Mufflers dampen the sound wave produced from the exhaust gas by bouncing it inside the muffler chamber.

Will no muffler hurt my engine?

No, it will not hurt your engine. The racers and performance enthusiasts mostly prefer driving their vehicles without any mufflers. But if you are using a good muffler, your vehicle is likely going to get a performance boost due to the backpressure it creates.

Can I put any muffler on my car?

Mufflers are mostly universal fit. You can fit any type of muffler in any vehicle. However, you should choose the muffler based on your engine power. Besides, the space underneath your car, inlet, and outlet diameter is also considerable. Though you can modify them according to your need.

Does removing the muffler increase horsepower?

Removing the muffler increases performance. But at the same time, you will hear more growling noise of the engine. This is not suitable for driving on the streets. However, some mufflers can reduce the noise as well as boost the performance. This is why it is recommended to use performance mufflers instead of removing it entirely.

Final Thoughts

As you can see, using a proper exhaust muffler is very important for your vehicle. The V6 engine is very powerful. If you can control the sound of it the whole driving experience will be a lot better. Moreover, some mufflers will drastically improve the performance of the vehicle. Hope this article will help you to choose the best muffler for a V6 engine vehicle.
