Best Exhaust For Subaru Wrx FAQs
Can installing an aftermarket exhaust on a Subaru WRX void the warranty?
Yes, installing an aftermarket exhaust on a Subaru WRX can potentially void the warranty. Most car manufacturers have specific guidelines regarding what kind of modifications are allowed on their vehicles without voiding the warranty. In the case of Subaru, modifying the exhaust system is considered a modification that can void the warranty if it causes damage to the engine or other components.
It is important to note that not all aftermarket exhausts will cause damage and void the warranty. Some exhaust systems are designed to improve performance without causing harm to the engine. However, it is always best to check with the manufacturer or dealership before making any modifications to your vehicle.
If you do decide to install an aftermarket exhaust on your Subaru WRX, it is recommended that you keep records of the installation and any maintenance or repairs done to the exhaust system. This way, if any issues arise with the vehicle, you can prove that the exhaust system was installed properly and did not cause any damage.
How does an aftermarket exhaust affect the performance of a Subaru WRX?
An aftermarket exhaust can significantly improve the performance of a Subaru WRX. The stock exhaust system is designed to meet certain regulations and standards, and it is not optimized for maximum performance. An aftermarket exhaust, on the other hand, is designed to provide better flow and reduce backpressure, which can lead to increased horsepower and torque.
In a Subaru WRX, an aftermarket exhaust can also provide a more aggressive exhaust note, which is a desirable feature for many performance enthusiasts. The exhaust system can also improve the overall driving experience by reducing weight and providing better throttle response.
It is important to note that the impact of an aftermarket exhaust on performance will vary depending on the specific model and the type of exhaust system installed. Some exhaust systems may provide a more significant performance boost than others, and it is important to choose an exhaust system that is compatible with the specific Subaru WRX model.
Overall, an aftermarket exhaust can have a positive impact on the performance and driving experience of a Subaru WRX, making it a popular upgrade for enthusiasts who want to maximize the potential of their vehicle.
How loud will a new exhaust system make my Subaru WRX?
The loudness of a new exhaust system for your Subaru WRX will depend on a variety of factors. Firstly, the type of exhaust system you choose, such as a cat-back or axle-back system, will impact the volume level. Secondly, the design and diameter of the exhaust piping, as well as the type of muffler used, will also affect the sound. Additionally, the material used for the exhaust, such as stainless steel or titanium, can also impact the volume level.
It's important to note that modifying your exhaust system can also affect the performance of your vehicle. While a louder exhaust may provide a sportier sound, it may also reduce your vehicle's backpressure, which can negatively impact acceleration and overall performance.
If you do choose to install a new exhaust system, it's recommended to consult with a professional mechanic or exhaust specialist to ensure that the system is installed correctly and that it meets your desired noise level and performance needs while staying within legal limits.
What are the differences between a cat-back and axle-back exhaust system for a Subaru WRX?
The main difference between a cat-back and axle-back exhaust system for a Subaru WRX lies in the components that are replaced. A cat-back system replaces the exhaust system from the catalytic converter back to the muffler, while an axle-back system replaces the exhaust system from the rear axle back to the muffler.
A cat-back system includes a new mid-pipe, resonator, and muffler, which can provide a more aggressive exhaust note and increased horsepower and torque. It also has a larger diameter pipe, which allows for better exhaust flow and less restriction.
An axle-back system, on the other hand, only replaces the muffler and tip, which can provide a slightly louder exhaust note and slightly improved performance, but not as significant as a cat-back system.
Overall, the choice between a cat-back and axle-back system for a Subaru WRX depends on the desired level of performance and sound. If you want a more aggressive exhaust note and improved performance, a cat-back system is the way to go. If you want a slightly louder exhaust note and a minor performance boost, an axle-back system may be sufficient.
What is the best exhaust system for a Subaru WRX?
When it comes to choosing the best exhaust system for your Subaru WRX, there are a few factors to consider. Firstly, you need to decide whether you want a cat-back or turbo-back exhaust system. A cat-back system replaces the exhaust system from the catalytic converter back, while a turbo-back system replaces everything from the turbocharger back.
One of the most popular exhaust systems for the Subaru WRX is the Cobb Tuning cat-back exhaust. It's made from high-quality stainless steel and is designed to improve exhaust flow, resulting in increased horsepower and torque. The Cobb Tuning exhaust also has a great sound, with a deep and aggressive tone that's not too loud.
Another great option is the Invidia N1 cat-back exhaust. It's made from high-quality stainless steel and features a straight-through design that maximizes exhaust flow. This exhaust system also has a loud and aggressive sound that's sure to turn heads.
Ultimately, the best exhaust system for your Subaru WRX will depend on your preferences and budget. Be sure to do your research and read reviews from other WRX owners before making a decision.
