Let's dive into the world of aftermarket exhausts for your 2014 Subaru Impreza Sport! If you're anything like me, you probably love the look and feel of your Impreza, but you're always looking for ways to make it even better. One of the most popular upgrades for Imprezas, especially the sport models, is upgrading the exhaust system. A new exhaust can enhance the sound, improve performance, and even give your car a more aggressive look. So, what do you need to know before you start shopping? Let's break it down, step by step, so you can make the best decision for your ride.

Why Upgrade Your Exhaust?

Before we get into specific options, let's talk about why you might want to upgrade your 2014 Subaru Impreza Sport's exhaust in the first place. There are several compelling reasons, and they often depend on what you're hoping to achieve with the upgrade. Most of the time, you are trying to achieve that rumble sound that you hear in other sports cars. So, let's get started.

Enhanced Sound

For many Impreza owners, the primary reason for upgrading the exhaust is to achieve a more aggressive and sporty sound. The stock exhaust on the 2014 Impreza Sport is fairly quiet, which is great for daily commuting but might leave you wanting more when you're looking for some excitement. An aftermarket exhaust can provide a deeper, throatier sound that announces your presence on the road. Different exhaust systems offer different tones, from a subtle rumble to a full-on roar, so you can choose one that matches your personal preference. Plus, who doesn't love the sound of a well-tuned exhaust when you're accelerating?

Improved Performance

While the sound is a big draw, an upgraded exhaust can also offer performance benefits. The stock exhaust system is designed to meet certain emissions standards and keep noise levels down, which can sometimes restrict the engine's ability to breathe efficiently. An aftermarket exhaust, especially one with larger diameter piping and a less restrictive muffler, can improve exhaust flow. This can result in a slight increase in horsepower and torque, particularly in the mid-range and upper RPMs. While you might not feel a massive difference, every little bit helps, right? Just remember, the performance gains will be more noticeable when paired with other modifications like an upgraded intake or ECU tune.

Aesthetic Appeal

Let's not forget about looks! An aftermarket exhaust can also enhance the visual appeal of your Impreza. Many exhaust systems come with polished stainless steel tips that look much sportier than the stock exhaust tip. Whether you prefer a single exit, dual exit, or even quad exit setup, there are plenty of options to choose from. Upgrading the exhaust can give your car a more custom and aggressive look, setting it apart from other Imprezas on the road. It’s all about making your ride uniquely yours.

Types of Exhaust Systems

Okay, so you're convinced that an exhaust upgrade is the way to go. Now, let's talk about the different types of exhaust systems available for your 2014 Subaru Impreza Sport. Understanding the different components and configurations will help you make an informed decision.

Cat-Back Exhaust

A cat-back exhaust system replaces everything from the catalytic converter back to the exhaust tip. This typically includes the mid-pipe, muffler, and exhaust tip. Cat-back systems are a popular choice because they offer a good balance of performance, sound, and affordability. They're also relatively easy to install, often requiring just basic hand tools. When choosing a cat-back system, pay attention to the piping diameter and muffler design. Larger diameter piping generally allows for better exhaust flow, while the muffler design will determine the sound characteristics of the exhaust. Look for systems made from high-quality materials like stainless steel to ensure durability and resistance to corrosion.

Axle-Back Exhaust

An axle-back exhaust system is a more budget-friendly option that replaces only the muffler and exhaust tip, from the rear axle back. Axle-back systems are primarily designed to enhance the sound of your Impreza, offering a quick and easy way to get a more aggressive tone. While they may not offer the same performance gains as a cat-back system, they're still a great choice if you're mainly focused on improving the sound. Installation is usually very straightforward, often requiring just a few bolts to be removed and replaced. Again, look for systems made from durable materials like stainless steel to ensure they can withstand the elements.

Header-Back Exhaust (Full Exhaust System)

For the ultimate performance upgrade, you might consider a header-back exhaust system, also known as a full exhaust system. This replaces everything from the engine's exhaust manifold (headers) all the way back to the exhaust tip. Header-back systems offer the most significant performance gains, as they completely remove the restrictive stock exhaust components. However, they're also the most expensive and complex to install, often requiring professional installation. When choosing a header-back system, make sure to check local emissions regulations, as some aftermarket headers may not be street legal. If you're serious about maximizing performance and don't mind the extra cost and effort, a header-back system can be a game-changer.

Key Features to Consider

Alright, now that you know the different types of exhaust systems, let's talk about some key features to consider when making your choice. These factors will influence the sound, performance, and overall quality of your exhaust.

Material

The material of the exhaust system is crucial for durability and longevity. Stainless steel is the most popular choice, as it offers excellent resistance to corrosion and can withstand high temperatures. Aluminized steel is a more affordable option, but it's not as resistant to rust and may not last as long in harsh climates. Titanium is the most expensive option, offering the best combination of lightweight and durability, but it's typically only found on high-end performance systems.

Piping Diameter

The diameter of the exhaust piping affects exhaust flow and, consequently, performance. Larger diameter piping generally allows for better exhaust flow, but going too large can actually reduce backpressure and hurt low-end torque. For a 2014 Subaru Impreza Sport, a 2.25-inch to 2.5-inch diameter exhaust is usually a good choice. This size provides a good balance of performance and drivability without sacrificing too much low-end torque.

Muffler Design

The muffler design plays a significant role in the sound characteristics of the exhaust. Chambered mufflers tend to produce a deeper, more aggressive sound, while straight-through mufflers offer a louder, more raspy tone. Some mufflers also incorporate resonators, which help to reduce unwanted frequencies and drone. Consider what kind of sound you're looking for and choose a muffler design that matches your preferences. Listening to sound clips online can be helpful in making your decision.

Brand and Quality

As with any aftermarket part, the brand and quality of the exhaust system matter. Reputable brands like Invidia, Borla, and MagnaFlow have a long history of producing high-quality exhaust systems that are designed to perform and last. Reading reviews and doing your research can help you avoid lower-quality systems that may not fit properly or may be prone to premature failure. Investing in a well-known brand can save you headaches in the long run.

Installation Tips

So, you've chosen your new exhaust system, and it's time to install it. Here are a few tips to make the installation process as smooth as possible.

Gather Your Tools

Before you start, make sure you have all the necessary tools. This typically includes a socket set, wrenches, a ratchet, penetrating oil, and jack stands. Having the right tools on hand will save you time and frustration.

Use Penetrating Oil

Old exhaust systems can be notoriously difficult to remove due to rust and corrosion. Generously apply penetrating oil to all the bolts and connections a day or two before you plan to start the installation. This will help loosen things up and make the removal process much easier.

Support the Car Safely

Always use jack stands to support the car when working underneath it. Never rely solely on a jack, as it can be dangerous. Make sure the car is stable and secure before you start working.

Follow the Instructions

Carefully read and follow the instructions that come with your exhaust system. Each system is different, and the instructions will provide specific guidance for your particular model. If you're not comfortable with the installation process, consider having it done by a professional.
