The Borla WRX downpipe is a popular upgrade among Subaru WRX enthusiasts looking to enhance both the sound and performance of their vehicles. This aftermarket component is designed to replace the factory downpipe, allowing for improved exhaust flow and a deeper, more aggressive tone.
What is a Downpipe?
A downpipe is a crucial part of a vehicle’s exhaust system. It connects the turbocharger to the rest of the exhaust system, playing a significant role in how exhaust gases are expelled from the engine. Upgrading to a performance downpipe can lead to several benefits, particularly for turbocharged engines like those found in the Subaru WRX.
Benefits of Upgrading to a Borla WRX Downpipe
- Improved Exhaust Flow: The Borla downpipe is designed with larger diameter piping, which reduces back pressure and allows exhaust gases to exit more efficiently.
- Enhanced Sound: One of the most noticeable changes is the deep, aggressive tone that the Borla downpipe produces, enhancing the overall driving experience.
- Increased Performance: By improving exhaust flow, the downpipe can help increase horsepower and torque, providing a noticeable performance boost.
- Durability: Made from high-quality materials, the Borla downpipe is built to withstand high temperatures and resist corrosion.
Installation Process
Installing the Borla WRX downpipe can be a rewarding project for those with basic mechanical skills. However, it is recommended to have a professional install it to ensure optimal performance and avoid potential issues. Here’s a general overview of the installation process:
- Preparation: Gather necessary tools, including wrenches, sockets, and any specific tools required for your WRX model.
- Lift the Vehicle: Use a jack and jack stands to safely lift the car, providing access to the undercarriage.
- Remove the Old Downpipe: Disconnect the factory downpipe from the turbo and exhaust system. This may require removing heat shields and other components.
- Install the Borla Downpipe: Position the new downpipe and secure it to the turbo and exhaust system, ensuring all connections are tight.
- Reassemble and Test: Reattach any components removed during installation, lower the vehicle, and start the engine to check for leaks and proper operation.
Sound Comparison
One of the primary reasons for upgrading to the Borla WRX downpipe is the sound enhancement. The factory downpipe often produces a subdued exhaust note, while the Borla downpipe delivers a more pronounced, aggressive sound. This change can significantly enhance the driving experience, making it more enjoyable for enthusiasts.
Performance Improvements
The performance gains from installing a Borla WRX downpipe can vary based on other modifications and tuning. However, many users report noticeable improvements in horsepower and torque, especially when paired with an aftermarket tune. The increased exhaust flow allows the turbocharger to spool more quickly, resulting in faster acceleration and improved throttle response.
Considerations Before Upgrading
Before purchasing a Borla WRX downpipe, there are several factors to consider:
- Legal Regulations: Ensure that the downpipe complies with local emissions regulations, as some areas have strict laws regarding aftermarket exhaust components.
- Tuning Requirements: To fully benefit from the performance improvements, an ECU tune may be necessary after installation.
- Compatibility: Verify that the downpipe is compatible with your specific WRX model and year.
Conclusion
The Borla WRX downpipe is an excellent choice for those looking to enhance their vehicle’s sound and performance. With its durable construction, improved exhaust flow, and deep tone, it is a worthwhile investment for any Subaru WRX enthusiast. Whether you are a seasoned mechanic or a first-time modifier, upgrading to a Borla downpipe can significantly enhance your driving experience.
