Honda Civic Sport 2020: Exhaust Upgrade Guide

Nov 17, 2025 by Alex Braham 46 views

Hey guys! Are you looking to boost your Honda Civic Sport 2020's performance and give it a more aggressive sound? You've landed in the right spot! Upgrading your exhaust system can significantly enhance your driving experience. Let’s dive into everything you need to know about choosing and installing the perfect exhaust for your ride.

Why Upgrade Your Honda Civic Sport 2020 Exhaust?

Let's get straight to the point. Why should you even bother upgrading your Honda Civic Sport 2020 exhaust? Well, the factory exhaust systems are often designed with mass production and noise reduction in mind. While they're perfectly adequate, they often restrict the engine's ability to breathe efficiently. Upgrading can unlock several benefits:

Increased Horsepower and Torque: A less restrictive exhaust system allows exhaust gases to exit the engine more freely. This reduces backpressure and can lead to noticeable gains in horsepower and torque, especially in the mid to high RPM ranges. You'll feel a difference when accelerating and passing other cars on the highway.
Improved Fuel Efficiency: While it might sound counterintuitive, a more efficient exhaust system can actually improve your fuel economy. When the engine doesn't have to work as hard to expel exhaust gases, it operates more efficiently, which can translate to better MPG.
Enhanced Sound: This is a big one for many enthusiasts. A performance exhaust can give your Civic Sport a deeper, more aggressive exhaust note. Say goodbye to the quiet, stock sound and hello to a throaty roar that turns heads wherever you go. Just make sure it's not so loud that your neighbors start complaining!
Aesthetic Appeal: Many aftermarket exhaust systems look fantastic, often featuring polished stainless steel or titanium tips. An upgraded exhaust can add a touch of style and personality to the rear of your Civic, making it stand out from the crowd.
Reduced Weight: Some aftermarket exhaust systems are made from lighter materials like stainless steel or titanium. This can reduce the overall weight of your car, which can improve handling and acceleration. Every little bit helps, right?

Types of Exhaust Systems for Your Civic Sport

Now that you know why to upgrade, let's talk about what to upgrade to. There are several types of exhaust systems available for the Honda Civic Sport 2020, each with its own characteristics and price point:

Axle-Back Systems: These are the simplest and most affordable option. An axle-back system replaces everything from the rear axle to the exhaust tip. They're easy to install and offer a noticeable improvement in sound and appearance. However, they typically don't offer significant performance gains.
Cat-Back Systems: Cat-back systems replace everything from the catalytic converter back to the exhaust tip. These offer a good balance of performance, sound, and price. They generally provide more noticeable horsepower and torque gains compared to axle-back systems.
Header-Back Systems (or Full Exhaust Systems): These are the most comprehensive and expensive option. A header-back system replaces everything from the exhaust manifold (headers) all the way to the exhaust tip. They offer the greatest potential for performance gains but are also the most complex to install.
Downpipes: The downpipe connects directly to the turbocharger (if applicable) and carries exhaust gases to the rest of the exhaust system. Upgrading the downpipe can significantly improve turbo response and power output. However, it may also require modifications to the ECU (engine control unit) to avoid error codes.

Choosing the right type of system depends on your budget, goals, and willingness to modify your car. An axle-back is a great option if you're mainly after sound and looks. A cat-back is a good all-around choice for performance and sound. A header-back is the way to go if you're looking for maximum power.

Key Considerations When Choosing an Exhaust

Alright, so you know the types of exhaust systems. But how do you actually pick the right one for your Honda Civic Sport 2020? Here are some crucial factors to keep in mind:

Material: Exhaust systems are typically made from either aluminized steel or stainless steel. Stainless steel is more durable and resistant to corrosion, making it a better long-term investment. Aluminized steel is more affordable but may rust over time, especially in areas with harsh weather conditions.
Pipe Diameter: The diameter of the exhaust pipes affects exhaust flow and backpressure. A larger diameter generally allows for better exhaust flow, but too large of a diameter can actually reduce performance by decreasing exhaust velocity. It's important to choose a pipe diameter that's appropriate for your engine's specifications and power goals.
Muffler Design: The muffler is responsible for controlling the sound level and tone of the exhaust. Different muffler designs produce different sounds, ranging from mild to aggressive. Research different muffler designs and listen to sound clips to get an idea of what you like. You don't want to end up with an exhaust that's too loud for your taste, or that drones annoyingly on the highway.
Brand Reputation: Stick with reputable brands that are known for producing high-quality exhaust systems. Do some research online and read reviews to see what other owners have to say about different brands and models. A well-known brand is more likely to have better quality control and customer support.
Installation: Consider whether you want to install the exhaust yourself or have it professionally installed. Some exhaust systems are easier to install than others. If you're not comfortable working on your car, it's best to leave the installation to a professional. Factor in the cost of installation when budgeting for your exhaust upgrade.
Legality: Be aware of local noise regulations and emissions laws. Some exhaust systems may not be legal in certain areas. Check your local laws before purchasing an exhaust to make sure it complies with all regulations.

Installation Tips and Considerations

Okay, you've picked out your exhaust. Now what? Here are some tips and things to consider before you start wrenching:

Tools: Make sure you have all the necessary tools before you begin the installation. This typically includes a socket set, wrench set, jack and jack stands, penetrating oil, and a torque wrench. Having the right tools will make the job much easier and prevent you from damaging your car or the exhaust system.
Safety: Always wear safety glasses and gloves when working on your car. Exhaust systems can be hot, and you don't want to burn yourself. Also, be sure to properly support your car with jack stands before getting underneath it.
Penetrating Oil: Spray all the bolts and nuts with penetrating oil a few hours before you start the installation. This will help loosen any rusted or seized fasteners and make them easier to remove.
Torque Specs: Use a torque wrench to tighten all the bolts and nuts to the manufacturer's specifications. Over-tightening can damage the bolts or the exhaust system, while under-tightening can cause leaks.
Hangers: Make sure to properly align the exhaust hangers and use new rubber isolators if necessary. This will prevent the exhaust system from rattling or vibrating against the car's chassis.
Professional Installation: If you're not comfortable installing the exhaust yourself, it's best to have it professionally installed. A professional installer will have the experience and tools to do the job correctly and ensure that the exhaust system is properly aligned and sealed.

Maintaining Your New Exhaust

Congrats on the new exhaust! Keep it looking and sounding great with these maintenance tips:

Regular Cleaning: Clean your exhaust system regularly to remove dirt, grime, and road salt. Use a mild soap and water solution and a soft cloth to wipe down the exhaust tips and pipes. Avoid using harsh chemicals or abrasive cleaners, as they can damage the finish.
Check for Leaks: Inspect your exhaust system regularly for leaks. Leaks can reduce performance and fuel efficiency, and they can also be dangerous. If you suspect a leak, have it repaired immediately.
Inspect Hangers: Check the exhaust hangers regularly to make sure they are in good condition. Replace any damaged or worn hangers to prevent the exhaust system from rattling or vibrating.
Avoid Harsh Driving: Avoid harsh driving habits such as excessive acceleration and deceleration. These habits can put extra stress on the exhaust system and shorten its lifespan.

Conclusion
