Upgrading the exhaust system on your Subaru WRX can significantly enhance the driving experience, improve performance, and give your car an aggressive sound. A WRX Catback exhaust system can bring these benefits, but choosing the best one requires careful consideration of various factors. In this guide, we'll explore why upgrading your exhaust is beneficial, how to select the best Catback system, and recommend some of the top options available.
Benefits of Upgrading to a WRX Catback Exhaust System
When you install a WRX Catback exhaust system, the impact on your car’s performance and sound is immediate. This upgrade can offer several tangible benefits.
1. Sound Improvement: The most obvious change you’ll experience is a boost in sound quality. A stock exhaust system on a WRX can be somewhat muted, but a high-quality Catback exhaust will give your car a more aggressive, deep, and throaty tone. For many enthusiasts, the sound of a turbocharged engine paired with a performance exhaust is a key part of the driving experience.
2. Performance Gains: A Catback exhaust system can improve your WRX's performance by optimizing exhaust flow. By reducing backpressure, the exhaust system allows the engine to breathe more freely, which leads to gains in horsepower and torque. Many users report increases of up to 10-20 horsepower, depending on the system and vehicle setup.
3. Appearance and Style: In addition to performance and sound, a WRX Catback exhaust can improve the visual appeal of your vehicle. Many systems come with large, polished tips, which add a sporty look to your WRX. A burnt titanium tip or quad exhaust setup can really make your car stand out on the road.
4. Fuel Efficiency: Although it might sound counterintuitive, a performance Catback exhaust system may help improve fuel efficiency. By reducing exhaust backpressure, the engine works more efficiently, which can translate into better fuel economy, especially during highway cruising.
Key Factors to Consider When Choosing a WRX Catback Exhaust
Selecting the right WRX Catback exhaust system involves several key factors. Here’s a breakdown of what to consider when making your decision.
1. Sound Profile
The sound is a key consideration when choosing a WRX Catback exhaust system. Some exhausts produce a deep, mellow tone, while others create a loud, aggressive growl. It’s important to select a system that matches your desired sound level. For example, if you want something that draws attention but isn’t unbearable, a system with a mid-level decibel range might be ideal.
2. Performance and Power Gains
Not all Catback exhausts offer the same performance benefits. Some are designed for optimal power gains, improving your WRX's horsepower, torque, and throttle response. If you’re focused on performance, look for systems designed to maximize airflow and reduce restrictions. Mandrel-bent tubing and larger diameter pipes often yield better results.
3. Material
When it comes to material, stainless steel is often the best choice due to its durability and resistance to rust. T-304 stainless steel is a top-tier material for high-performance systems. It can withstand high temperatures and resist corrosion, ensuring a longer lifespan for your exhaust system.
4. Compatibility
Always ensure that the Catback exhaust system you choose is compatible with your specific WRX model and year. Some systems are designed for 2015-2021 WRX models, while others are better suited for 2008-2014 WRX STIs. Check the fitment specifications to avoid unnecessary complications during installation.
5. Budget and Value

WRX Catback Exhaust System Myths and Misconceptions
Upgrading your exhaust can be an exciting process, but it’s also crucial to debunk common myths and misconceptions surrounding WRX Catback exhaust systems. Let’s address a few misconceptions that often confuse potential buyers.
1. "A Catback Exhaust Will Make Your Car Unbearably Loud"
One of the most common myths is that replacing the stock exhaust with a Catback exhaust system will create an obnoxiously loud car. While some systems are designed for maximum sound output, many high-quality Catback systems are engineered to provide a more refined, deep tone that enhances the driving experience without being intrusive.
2. "More Expensive Exhausts Always Offer More Power"
While it’s true that higher-end systems often use better materials (like T-304 stainless steel) and more efficient designs, a higher price doesn’t always guarantee greater performance. In some cases, mid-range systems can offer similar performance gains at a lower cost, so it’s essential to balance cost with the actual benefits the system offers.
3. "Catback Exhaust Systems Only Improve Performance on High-Performance Cars"
Another myth is that Catback exhausts are only for high-performance cars. In reality, even stock WRXs benefit from the increased airflow and reduced backpressure that come with a quality Catback exhaust. These systems improve throttle response and power delivery, making your WRX feel more responsive on the road.
4. "All Catback Exhaust Systems Are the Same"
Not all Catback exhausts are created equal. Factors such as the design of the muffler, pipe diameter, material quality, and even the tip style can vary significantly from one system to another. Always read reviews and specifications carefully before purchasing to ensure you get the best system for your needs.
