What to Consider When Buying Best Exhaust For Mustang GT

The Mustang GT can be total beasts if paired with the right parts. That means that finding the ideal exhaust system is very important.

It’ll help the cars perform both aggressively and with outstanding power. But, how to find the best exhaust for Mustang GT?

Simple: by learning about the features listed here.

Construction

First, the biggest concern before purchasing an exhaust system should be its construction.

The materials and the technology used to play a massive role in the service life of the exhaust. Plus, the build is also a fantastic indicator of the quality of the product overall.

So, what to look for here? It’s pretty easy, actually: look for an exhaust system made of stainless steel.

Stainless steel guarantees the exhaust will last a long time. This material is durable and reliable, two qualities that car owners always need. Plus, you won’t have to worry about rust, corrosion, or decoloration issues either.

Size

While the diameter of the tubing and tips vary, there are some average sizes for reference.

For instance, an estimated ideal size for the tubing would be 2.75-inch. This diameter is perfect for improving airflow and delivering a loud performance. A clear example of this is the Borla 140590BC Exhaust System.

The tip size is also essential. Again, this can also be different from brand to brand. But, the average diameter size is 4-inch for the exhaust tips.

Just like before, this is enough to receive proper airflow and make the Mustang GT sound as good as possible.

Finish

 

Most exhaust systems have a polished stainless steel finish. But, the design can be different depending on the brand. Choosing which one to get depends on personal preferences, so it’s up to you.

Regardless of which one you choose, make sure the finish is durable. It should be able to put up with the abuse of regular cruising.

Plus, it must also be strong enough to withstand the exhaust heat. There’s also the Mustang GT titanium exhaust, which also looks fantastic.

Since the Mustang GT is already a fantastic series of cars, it’s only natural to buy parts that look just as good. A powerful exhaust with a beautiful and shiny finish will do that.

Sound Quality

The sound produced by an exhaust system varies a lot. While idle, it can have a deep low growl. This is not the same while accelerating. At high speeds, the exhaust can produce an aggressive roar on the roads.

Whether the exhaust produces quality sounds depends on several factors. Some of which are the build material, the size, and the shape of the tips.

Keeping the tubing system in perfect condition is a must. This will allow the exhaust to perform consistently.

With a durable build, there won’t be any loss in power and sound quality.

Drone

During the reviews, you may have noticed the mention of “drone” several times. But what does this mean, exactly?

Drone refers to a monotone sound and vibration experienced with aftermarket exhaust systems.

Though it may be minimal, it gets increasingly frustrating over time. You’re driving a Mustang GT, for Christ’s sake!

These cars should ride smoothly and without complications.

But exhaust drone is a real thing, and it’s better to avoid it beforehand. While looking for an exhaust system, make sure this isn’t an issue you’d have to face later on.

An excellent way to avoid this problem is by reading reviews as much as possible.

Ease of Installation

Typically, installing an exhaust may take between one or two hours. Whether it takes more or less than that depends a lot on the exhaust model, too.

Some exhaust systems come well-packaged with all the parts needed for the mounting. Of course, this means you’ll have to spend less time searching for extra parts. It’s also less costly and super convenient.

But that’s not always the case. Other systems may not have instructions, or they may be missing some parts. As a result, you’d have to spend more time and more money to get the job done.

Weight

The weight of an exhaust system isn’t essential, but it’s still something to consider. Mustang GT cars are popular due to their power, which depends on speed and sound quality. Lightweight exhausts could take a significant burden out of your vehicle.

Besides, lightweight units are much easier to handle. This comes in handy during the installation, which may take hours.

Also, installing the exhaust may need modifications and alignment. If that’s the case, the last thing you want is to carry a heavy exhaust around.

Conclusion

Don’t let your amazing Mustang GT go unnoticed anymore. The products reviewed here can help you find the best exhaust for Mustang GT to improve its power and looks.

Before choosing one, make sure to consider all the considerations shared here.

If you do, you’ll be boasting all the power a Mustang GT can offer. It’ll be the envy of your friends, and it’ll grab everyone’s attention on the roads.
