When the engine doesn't have to work as hard to expel exhaust gases, it can operate more efficiently, potentially saving you money at the pump. Plus, let's not forget about the visual appeal. Many aftermarket exhausts come with stylish tips and designs that can enhance the look of your car. Whether you prefer a subtle, understated look or a bold, aggressive one, there's an exhaust out there that will match your style. Upgrading your exhaust is more than just a cosmetic change, it's an investment in your car's performance and your driving enjoyment. It’s about making your Impreza Sport truly your own and experiencing the road with a newfound sense of excitement.

Types of Exhaust Systems for Your Impreza

Alright, let's get into the nitty-gritty of the different types of exhaust systems you can get for your 2014 Impreza Sport. Understanding the options available is crucial for making the right choice.

Cat-Back Exhaust Systems

First up, we have cat-back exhaust systems. These systems replace everything from the catalytic converter back to the exhaust tip. This typically includes the mid-pipe and the muffler. Cat-back systems are a popular choice because they offer a good balance of performance gains, sound improvement, and ease of installation. Since they don't involve modifying the catalytic converter, they're also generally emissions-legal in most areas. The main advantage of a cat-back system is that it improves exhaust flow without requiring extensive modifications to your car's emissions system. This makes it a relatively straightforward upgrade that can provide noticeable benefits in terms of sound and performance. Plus, you get a shiny new exhaust tip to show off! Choosing the right cat-back system involves considering the materials used, such as stainless steel or aluminized steel, the diameter of the piping, and the design of the muffler. These factors will influence the sound, performance, and durability of the exhaust. Make sure to research different brands and read reviews to find a system that meets your specific needs and preferences. A well-chosen cat-back exhaust can transform your driving experience, adding a sporty edge to your Impreza Sport without breaking the bank or causing headaches with emissions regulations.

Axle-Back Exhaust Systems

Next, we have axle-back exhaust systems. These are even simpler than cat-back systems, replacing only the components from the rear axle to the exhaust tip, primarily the muffler. Axle-back systems are a great option if you're primarily looking for a change in sound without significantly altering performance. Installation is usually very straightforward, often requiring just basic hand tools. The main appeal of an axle-back system is its simplicity and affordability. It's a quick and easy way to enhance the sound of your exhaust without making major modifications to your car. If you're on a budget or just want a subtle upgrade, an axle-back system might be the perfect choice. However, keep in mind that the performance gains from an axle-back system are typically minimal compared to a cat-back system. The primary focus is on improving the exhaust note and adding a bit of visual flair with a new exhaust tip. When selecting an axle-back system, pay attention to the muffler design and the materials used. Different mufflers will produce different sounds, so listen to sound clips and read reviews to get an idea of what to expect. Stainless steel mufflers are generally more durable and resistant to corrosion than aluminized steel mufflers. Ultimately, an axle-back exhaust system is a great entry-level upgrade that can add some excitement to your Impreza Sport without requiring a lot of time, money, or effort.

Full Exhaust Systems (Headers, Downpipes, etc.)

For those who want the ultimate performance upgrade, there are full exhaust systems. These systems replace everything from the engine's exhaust manifold (headers) to the exhaust tip. This includes the headers, downpipe, catalytic converter (or a high-flow cat), mid-pipe, and muffler. Full exhaust systems offer the most significant performance gains, but they also require the most extensive modifications and may not be emissions-legal in all areas. The key advantage of a full exhaust system is its ability to maximize exhaust flow, resulting in noticeable increases in horsepower and torque. By replacing the restrictive stock components with high-flow alternatives, the engine can breathe more freely, leading to improved performance across the board. However, installing a full exhaust system can be a complex and time-consuming process, often requiring specialized tools and expertise. It's also important to consider the emissions implications of removing or replacing the catalytic converter. In many areas, it's illegal to remove the catalytic converter, and doing so can result in fines and failed emissions tests. If you're considering a full exhaust system, it's essential to research the local laws and regulations regarding emissions. You may also want to consider a high-flow catalytic converter, which can improve exhaust flow while still maintaining emissions compliance. A full exhaust system is a serious upgrade that can transform the performance of your Impreza Sport, but it's crucial to weigh the benefits against the potential drawbacks before making a decision.

Factors to Consider When Choosing an Exhaust

Choosing the right exhaust system for your 2014 Subaru Impreza Sport involves considering several key factors. You want to make sure you're getting the best bang for your buck and that the exhaust you choose aligns with your goals and preferences. Let's break down the most important things to keep in mind.

Sound

First and foremost, sound is a major consideration for most people. What kind of exhaust note are you looking for? Do you want a deep, aggressive rumble, or something more subtle and refined? The sound of your exhaust can significantly impact your driving experience, so it's important to choose wisely. Different exhaust systems will produce different sounds depending on their design and construction. Muffler design plays a crucial role in shaping the exhaust note. Chambered mufflers tend to produce a more aggressive, throaty sound, while straight-through mufflers offer a louder, more free-flowing tone. The diameter of the exhaust piping can also affect the sound, with larger diameter pipes generally resulting in a louder exhaust. It's a good idea to listen to sound clips of different exhaust systems before making a decision. Many manufacturers and retailers provide audio or video samples of their exhausts, allowing you to get an idea of what they sound like in real life. You can also find sound clips on YouTube and other online forums. Remember, sound is subjective, so what sounds good to one person may not sound good to another. Take the time to listen to different options and choose an exhaust that matches your personal preferences. The goal is to find an exhaust that enhances your driving enjoyment without being obnoxious or annoying.

Performance

While sound is important, performance is another critical factor to consider. An upgraded exhaust system can improve your car's horsepower, torque, and fuel efficiency. However, not all exhausts are created equal, and some may offer more performance gains than others. When evaluating exhaust systems, look for those that are designed to reduce backpressure and improve exhaust flow. Less restrictive exhausts allow the engine to breathe more easily, resulting in increased power and efficiency. Cat-back and full exhaust systems typically offer the most significant performance gains, as they replace a larger portion of the factory exhaust system. Axle-back systems, on the other hand, tend to provide more modest performance improvements. The diameter of the exhaust piping can also affect performance. Larger diameter pipes generally allow for greater exhaust flow, but it's important to choose a size that is appropriate for your engine. Too large of a diameter can actually decrease performance by reducing exhaust velocity. It's also important to consider the quality of the materials used in the exhaust system. Stainless steel exhausts are generally more durable and resistant to corrosion than aluminized steel exhausts, which can help ensure that your exhaust system performs optimally for years to come. Ultimately, the best exhaust for performance is one that is designed to maximize exhaust flow while maintaining appropriate backpressure and durability.

Budget

Let's be real, budget is always a consideration. Exhaust systems can range from a few hundred dollars to over a thousand, so it's important to set a budget and stick to it. Axle-back systems are generally the most affordable option, followed by cat-back systems. Full exhaust systems tend to be the most expensive, due to the increased complexity and the number of components involved. When setting your budget, it's important to consider not only the cost of the exhaust system itself but also the cost of installation. If you're not comfortable installing the exhaust yourself, you'll need to factor in the cost of labor. Installation costs can vary depending on the complexity of the job and the labor rates in your area. It's also a good idea to factor in some extra money for unexpected expenses. You never know what kind of issues you might encounter during the installation process, so it's always best to be prepared. When shopping for an exhaust system, be sure to compare prices from different retailers. You may be able to find a better deal by shopping around. Don't be afraid to ask for discounts or negotiate prices. Many retailers are willing to offer discounts, especially if you're paying in cash. Remember, the most expensive exhaust system is not always the best. There are plenty of high-quality, affordable exhausts that can provide excellent sound and performance without breaking the bank. Do your research, read reviews, and choose an exhaust that fits your budget and your needs.

Emissions

Finally, you need to think about emissions. Depending on where you live, there may be laws and regulations regarding exhaust modifications. It's important to choose an exhaust system that is emissions-legal in your area to avoid fines and failed inspections. In many areas, it's illegal to remove or modify the catalytic converter. If you're considering an exhaust system that replaces the catalytic converter, make sure it is CARB-compliant (California Air Resources Board) or meets the emissions standards in your state. Some exhaust systems come with a high-flow catalytic converter, which can improve exhaust flow while still maintaining emissions compliance. These systems are a good option if you want to improve performance without violating emissions laws. It's also important to consider the sound level of your exhaust. Some areas have noise restrictions, and excessively loud exhausts can result in fines. Before purchasing an exhaust system, check the local laws and regulations regarding exhaust modifications and noise levels. You can usually find this information on your state's Department of Motor Vehicles website. Choosing an emissions-legal exhaust system is not only important for avoiding legal trouble but also for protecting the environment. By reducing emissions, you can help improve air quality and reduce your carbon footprint. When in doubt, it's always best to err on the side of caution and choose an exhaust system that is known to be emissions-legal in your area.
