Before we jump into the upgrades, let's quickly cover the basics of your 2013 Honda Accord Coupe's exhaust system. The exhaust system is more than just a way to get rid of fumes; it plays a crucial role in your car's performance and fuel efficiency. Understanding the components and how they work together will help you make informed decisions about upgrades.

The primary components of your exhaust system include:

• Exhaust Manifold: This collects exhaust gases from the engine cylinders and directs them into the exhaust system.
• Catalytic Converter: This reduces harmful emissions by converting pollutants into less harmful substances.
• Resonator: This helps to reduce noise and control exhaust tone.
• Muffler: This is the final noise-reducing component in the system.
• Piping: These connect all the components, allowing exhaust gases to flow through the system.

When you're considering an exhaust upgrade, think about how each component affects the overall performance and sound. For example, a high-flow catalytic converter can improve exhaust flow, leading to better horsepower, while a performance muffler can give your Accord a more aggressive sound. Stock exhaust systems are often designed with cost and noise reduction in mind, which can sometimes restrict performance. Upgrading to aftermarket components can unlock hidden potential in your engine. Also, keep in mind that modifications to your exhaust system may need to comply with local regulations, so it's always a good idea to check before making any changes. By understanding these basics, you'll be well-equipped to choose the right exhaust upgrades for your 2013 Honda Accord Coupe.

Exploring Muffler Options

Alright, let's kick things off with muffler options for your 2013 Honda Accord Coupe. Swapping out your stock muffler is often the easiest and most budget-friendly way to change the sound of your exhaust. You can find mufflers in a variety of styles, materials, and sound levels, so you're sure to find one that suits your taste.

• Axle-Back Mufflers: These are designed to replace the stock muffler and typically bolt directly onto the existing exhaust piping. They are simple to install and offer a noticeable change in exhaust tone. If you're looking for a quick and easy upgrade without breaking the bank, an axle-back muffler is a great choice.
• Performance Mufflers: These are designed to provide better exhaust flow and a more aggressive sound. They often feature larger internal diameters and less restrictive designs compared to stock mufflers. Common brands include MagnaFlow, Flowmaster, and Borla. Each brand has its own unique sound characteristics, so do some research and listen to sound clips before making a decision. For instance, MagnaFlow typically offers a smooth, deep tone, while Flowmaster is known for its aggressive, muscular sound.
• Universal Mufflers: If you're on a tight budget or want a more customized setup, you can opt for a universal muffler. These mufflers can be adapted to fit various vehicles but may require some welding or fabrication. Keep in mind that installation might be a bit more involved compared to bolt-on options.

When selecting a muffler, consider the material as well. Stainless steel mufflers are more durable and resistant to corrosion than aluminized steel mufflers. While they may cost a bit more upfront, they will likely last longer and maintain their appearance over time. Remember to check customer reviews and listen to sound clips to get a good idea of how the muffler will sound on your specific vehicle. Pay attention to whether the sound is described as deep, raspy, or mellow, and choose one that aligns with your personal preference. With the right muffler, you can transform the sound of your 2013 Honda Accord Coupe and make it stand out from the crowd.

Diving into Cat-Back Exhaust Systems

Ready to take your exhaust upgrade to the next level? A cat-back exhaust system replaces everything from the catalytic converter back to the exhaust tips. This includes the resonator, muffler, and all the connecting pipes. Cat-back systems are designed to improve exhaust flow, increase horsepower, and enhance the sound of your 2013 Honda Accord Coupe. Let's explore the different options.

• Performance Gains: Cat-back systems are engineered to reduce exhaust backpressure, allowing your engine to breathe more efficiently. This can result in noticeable gains in horsepower and torque, especially in the mid-range and upper RPMs. Many manufacturers provide dyno results to showcase the performance improvements you can expect from their systems. While the gains may vary depending on other modifications and the specific system, you can generally expect an increase of 5-15 horsepower.
• Sound Enhancement: One of the primary reasons people upgrade to a cat-back system is for the improved sound. These systems offer a deeper, more aggressive exhaust note compared to the stock system. You can choose from a variety of sound levels, ranging from mild to aggressive, depending on your personal preference. Some systems also feature adjustable exhaust valves, allowing you to control the sound level with the push of a button.
• Material and Construction: Cat-back systems are typically made from stainless steel or aluminized steel. Stainless steel systems are more durable and resistant to corrosion, making them a worthwhile investment if you live in an area with harsh weather conditions. Aluminized steel systems are more affordable but may not last as long. Look for systems with mandrel-bent piping, which ensures smooth exhaust flow and minimizes restrictions. Also, check the thickness of the steel; thicker steel will generally be more durable and resistant to damage.
• Installation: Installing a cat-back system is more involved than installing an axle-back muffler, but it can still be done at home with the right tools and some mechanical knowledge. Most systems come with detailed instructions and all the necessary hardware. However, if you're not comfortable working on your car, it's best to have a professional install the system. This will ensure proper fitment and avoid any potential issues.

Before purchasing a cat-back system, research different brands and read customer reviews. Look for systems that are specifically designed for your 2013 Honda Accord Coupe to ensure proper fitment and optimal performance. Consider your budget and how much you value durability when choosing between stainless steel and aluminized steel. With the right cat-back system, you can significantly improve the performance and sound of your ride.

Considering Headers and Downpipes

For the serious performance enthusiasts, upgrading your headers and downpipes can provide even greater gains. Headers replace the stock exhaust manifold, while downpipes connect the turbocharger (if applicable) to the rest of the exhaust system. These components are designed to maximize exhaust flow and unlock even more horsepower and torque.

• Headers: Stock exhaust manifolds are often restrictive, limiting the engine's ability to breathe. Aftermarket headers feature larger diameter tubing and smoother bends, allowing exhaust gases to flow more freely. There are two main types of headers: shorty headers and long tube headers. Shorty headers offer a modest improvement in exhaust flow and are easier to install. Long tube headers, on the other hand, provide a more significant performance boost but require more extensive modifications and may not be legal in all areas.
• Downpipes: If your 2013 Honda Accord Coupe is turbocharged (though unlikely, as this generation Accord was not typically turbocharged), the downpipe is a crucial component for improving performance. The stock downpipe often contains a restrictive catalytic converter that limits exhaust flow. Upgrading to a high-flow downpipe can significantly reduce backpressure and increase horsepower. However, keep in mind that removing or modifying the catalytic converter may not be legal in your area.

When selecting headers and downpipes, consider the material, design, and fitment. Stainless steel is the preferred material for its durability and resistance to corrosion. Look for headers with equal-length runners, which ensure that exhaust gases from each cylinder reach the collector at the same time, resulting in smoother and more efficient exhaust flow. Also, make sure the headers and downpipes are specifically designed for your 2013 Honda Accord Coupe to ensure proper fitment.

Installing headers and downpipes is a more complex process than installing a muffler or cat-back system. It often requires removing other components and may involve some welding or fabrication. If you're not experienced with this type of work, it's best to have a professional install them. Keep in mind that upgrading your headers and downpipes may also require a tune to optimize the engine's performance and prevent any potential issues.

Before making any modifications, research local laws and regulations regarding exhaust modifications. Some areas have strict noise restrictions or require vehicles to pass emissions tests. Make sure your upgrades comply with these regulations to avoid any legal issues. With the right headers and downpipes, you can unleash the full potential of your 2013 Honda Accord Coupe's engine and experience a significant improvement in performance.

Choosing the Right Exhaust Tips

While they don't affect performance, exhaust tips can add a stylish touch and complement your other modifications. You can choose from a variety of styles, sizes, and finishes to create a custom look.

• Styles: Exhaust tips come in various shapes, including round, oval, square, and angled. You can also choose from single-wall or double-wall designs. Single-wall tips have a simple, clean look, while double-wall tips offer a more polished and refined appearance. The choice is ultimately a matter of personal preference.
• Sizes: The size of the exhaust tip should be proportional to the size of your exhaust piping and the overall look of your car. A tip that's too small may look out of place, while a tip that's too large may appear excessive. Measure the diameter of your exhaust piping and choose a tip that's slightly larger for a seamless fit.
• Finishes: Exhaust tips are available in various finishes, including chrome, polished stainless steel, black, and titanium. Chrome tips offer a classic, shiny look, while polished stainless steel tips provide a more subtle and understated appearance. Black tips add a sporty and aggressive touch, while titanium tips offer a unique and high-end look.

When selecting exhaust tips, consider the overall style of your car and your personal preferences.
