Hey guys! Thinking about upgrading your 2011 Subaru Legacy's exhaust system? You've come to the right place! Let's dive into everything you need to know to make an informed decision and get the most out of your ride. This guide will cover why you might want to upgrade, what to look for in a new exhaust system, and some top recommendations.

Why Upgrade Your 2011 Subaru Legacy's Exhaust System?

So, why should you even bother upgrading your 2011 Subaru Legacy exhaust system? There are several compelling reasons, from boosting performance to enhancing your car's sound and appearance. Let's break it down:

• Performance Enhancement: One of the primary reasons people upgrade their exhaust systems is to improve engine performance. The stock exhaust system in your 2011 Subaru Legacy is designed to meet certain emissions and noise standards, which can restrict the engine's ability to breathe efficiently. An aftermarket exhaust system, especially a cat-back or axle-back system, can reduce backpressure, allowing the engine to exhale more easily. This results in increased horsepower and torque, giving you a noticeable boost in acceleration and overall driving experience. Imagine feeling that extra oomph when you hit the gas pedal – that's what a performance exhaust can do for you!
• Improved Fuel Efficiency: While it might sound counterintuitive, an upgraded exhaust system can also improve your fuel efficiency. By reducing backpressure and allowing the engine to operate more efficiently, it requires less energy to produce the same amount of power. This can translate to a slight but noticeable improvement in your gas mileage, especially on long drives. Think of it as a win-win: more power and fewer trips to the gas station!
• Enhanced Sound: Let's face it – the stock exhaust sound on most cars is pretty tame. If you're looking to add some character and aggression to your 2011 Subaru Legacy, an aftermarket exhaust system is a fantastic way to do it. You can choose from a variety of exhaust notes, from a deep, throaty rumble to a more aggressive, high-pitched growl. The sound of your car can make a huge difference in how you feel behind the wheel, turning your daily commute into a more engaging and enjoyable experience. Imagine cruising down the street with that perfect exhaust note turning heads – that's the power of a great sounding exhaust!
• Aesthetic Appeal: An upgraded exhaust system isn't just about performance and sound; it can also enhance the visual appeal of your car. Many aftermarket exhaust systems feature polished stainless steel tips or other stylish designs that can give your 2011 Subaru Legacy a sportier and more aggressive look. Whether you're going for a subtle upgrade or a more dramatic transformation, a new exhaust system can definitely make your car stand out from the crowd. Think of it as adding a touch of personal style to your ride – a visual statement that reflects your passion for cars!
• Weight Reduction: Some aftermarket exhaust systems are made from lighter materials, such as stainless steel or titanium, compared to the stock system. This can result in a small but noticeable reduction in overall vehicle weight, which can further improve performance and handling. While the weight savings might not be huge, every little bit helps when it comes to optimizing your car's performance. Imagine shedding a few pounds and feeling the difference in your car's responsiveness – that's the benefit of a lightweight exhaust system!

Types of Exhaust Systems for Your 2011 Subaru Legacy

Okay, so you're convinced that upgrading your exhaust is a good idea. Now, let's talk about the different types of exhaust systems available for your 2011 Subaru Legacy. Each type offers different levels of performance, sound, and price, so it's important to choose the one that best fits your needs and budget.

• Axle-Back Exhaust Systems: An axle-back exhaust system replaces everything from the rear axle to the exhaust tips. This is generally the most affordable and easiest to install type of aftermarket exhaust. Axle-back systems primarily focus on improving the sound and appearance of your car, with modest gains in performance. If you're looking for a quick and easy way to add some rumble to your 2011 Subaru Legacy without breaking the bank, an axle-back system is a great option. Installation is typically straightforward, often requiring just basic hand tools and a little bit of elbow grease. You'll get a more aggressive exhaust note and a sportier look, enhancing your driving experience without major modifications.
• Cat-Back Exhaust Systems: A cat-back exhaust system replaces everything from the catalytic converter to the exhaust tips. This type of system offers a more significant performance boost compared to an axle-back system, as it replaces a larger portion of the exhaust piping. Cat-back systems also tend to offer a more aggressive sound. If you're looking for a balance of performance, sound, and affordability, a cat-back system is an excellent choice. Installation is a bit more involved than an axle-back system, but it's still manageable for most DIY enthusiasts. You'll notice improved throttle response and a more pronounced exhaust note, making your 2011 Subaru Legacy feel more powerful and responsive.
• Turbo-Back Exhaust Systems: A turbo-back exhaust system (only applicable if your Legacy has a turbo) replaces the entire exhaust system from the turbocharger to the exhaust tips. This is the most comprehensive and performance-oriented type of exhaust system. Turbo-back systems offer the greatest gains in horsepower and torque, as they remove all restrictions in the exhaust flow. They also produce the most aggressive sound. However, turbo-back systems are also the most expensive and may require professional installation. If you're serious about maximizing the performance of your turbocharged 2011 Subaru Legacy and don't mind spending the extra money, a turbo-back system is the way to go. You'll experience a significant improvement in power and responsiveness, transforming your car into a true performance machine.
• Header-Back Exhaust Systems: Similar to turbo-back systems, header-back systems replace everything from the exhaust manifold (headers) to the exhaust tips. This is another comprehensive option for naturally aspirated engines, offering substantial performance gains by optimizing exhaust flow from the engine. Like turbo-back systems, they can be more expensive and may require professional installation. For those seeking maximum performance improvements on a non-turbocharged Legacy, a header-back system provides a complete exhaust upgrade.

Factors to Consider When Choosing an Exhaust System

Alright, now that you know the different types of exhaust systems, let's talk about the factors you should consider when making your choice. This will help you narrow down your options and find the perfect exhaust system for your 2011 Subaru Legacy.

• Sound Level and Tone: One of the most important considerations is the sound level and tone of the exhaust system. Do you want a subtle rumble or a loud, aggressive growl? Keep in mind that some exhaust systems can be quite loud, which may not be suitable for daily driving or residential areas. It's a good idea to listen to sound clips or videos of different exhaust systems before making a decision. Consider what kind of driving you do most often. A louder exhaust might be fun for weekend cruises, but it could become tiresome on long commutes. Think about the overall tone as well – do you prefer a deep, throaty sound or a higher-pitched, raspy note? Your personal preference is key here, so take the time to explore different options and find the sound that you truly love. Remember, the goal is to enhance your driving experience, not to annoy your neighbors!
• Material and Durability: The material of the exhaust system is another important factor to consider. Stainless steel is a popular choice due to its durability and resistance to corrosion. Titanium is another option, offering even greater weight savings and corrosion resistance, but it's also more expensive. Aluminized steel is a more affordable option, but it's not as durable as stainless steel or titanium. Consider the climate in your area and how much exposure your car will have to harsh weather conditions. If you live in an area with a lot of salt or snow, stainless steel or titanium is definitely worth the investment to prevent rust and corrosion. Think about how long you plan to keep your car. If you're planning on driving it for many years, a more durable material will ensure that your exhaust system lasts the distance. Ultimately, the material you choose will depend on your budget and your priorities in terms of durability and longevity.
• Installation Difficulty: Consider your mechanical skills and whether you're comfortable installing the exhaust system yourself. Axle-back systems are generally the easiest to install, while cat-back and turbo-back systems may require more expertise and tools. If you're not comfortable doing the installation yourself, you'll need to factor in the cost of professional installation. Before you start the installation, make sure you have all the necessary tools and equipment. Read the instructions carefully and watch some online tutorials to get a better understanding of the process. If you encounter any difficulties, don't hesitate to seek help from a qualified mechanic. Remember, safety should always be your top priority, so take your time and be careful not to damage any components.
• Price: Exhaust systems can range in price from a few hundred dollars to over a thousand dollars, so it's important to set a budget before you start shopping. Keep in mind that the price will vary depending on the type of system, the material, and the brand. Don't automatically go for the cheapest option, as it may not be the best quality. Instead, focus on finding the best value for your money. Consider the long-term cost of ownership. A more expensive exhaust system made from durable materials may last longer and require less maintenance, saving you money in the long run. Read reviews and compare prices from different retailers to get the best deal. And don't forget to factor in the cost of installation if you're not planning on doing it yourself. By doing your research and setting a realistic budget, you can find an exhaust system that fits your needs and your wallet.
• Brand Reputation and Reviews: Do your research and choose a reputable brand with a proven track record of quality and performance. Read online reviews to see what other customers have to say about the exhaust system you're considering. A good brand will stand behind its products and offer excellent customer support. Look for brands that have been in the business for a long time and have a reputation for innovation and reliability. Pay attention to the details in the reviews – are customers praising the sound quality, the performance gains, or the ease of installation? Are there any common complaints about the exhaust system, such as poor fitment or premature rusting? By reading reviews and doing your research, you can get a better understanding of the pros and cons of different exhaust systems and make a more informed decision. Remember, choosing a reputable brand is an investment in your car's performance and your peace of mind.
