The 2012 Subaru WRX is a beloved choice among car enthusiasts, known for its performance and tuning potential. One of the simplest modifications that can yield noticeable results is the resonator delete. In this article, we will explore how a $60 resonator delete can add 12 horsepower to your WRX.
Understanding the Resonator Delete
A resonator delete involves removing the factory resonator from the exhaust system. The resonator’s primary function is to reduce noise and modify the exhaust tone. While this can create a quieter and more refined sound, many enthusiasts prefer a more aggressive exhaust note.
Benefits of a Resonator Delete
- Improved Sound: A resonator delete typically results in a deeper and more aggressive exhaust note.
- Weight Reduction: Removing the resonator can slightly reduce the overall weight of the vehicle.
- Increased Performance: The deletion can help improve exhaust flow, potentially leading to a horsepower increase.
Installation Process
Installing a resonator delete is a straightforward process that can be accomplished with basic tools. Here’s a step-by-step guide:
- Gather Tools: You will need a jack, jack stands, socket set, and a sawzall or exhaust pipe cutter.
- Lift the Vehicle: Safely lift the car using a jack and secure it with jack stands.
- Locate the Resonator: Identify the resonator in the exhaust system, typically located between the downpipe and the muffler.
- Cut the Resonator: Use the sawzall or pipe cutter to remove the resonator carefully.
- Install a Straight Pipe: Replace the resonator with a straight pipe, ensuring it is securely fastened.
- Check for Leaks: Start the engine and check for any exhaust leaks around the new connection.
Real Owner Results
After completing the resonator delete, many Subaru WRX owners have reported significant performance gains. In a real-world scenario, one owner documented a 12 horsepower increase after the modification. This was measured on a dynamometer, providing concrete evidence of the performance boost.
Considerations Before Modifying
While a resonator delete can enhance performance and sound, there are several considerations to keep in mind:
- Legal Regulations: Ensure that removing the resonator complies with local emissions laws.
- Noise Levels: Be prepared for a louder exhaust note, which may not be suitable for all drivers.
- Warranty Implications: Modifications may affect your vehicle’s warranty; check with your dealer.
Conclusion
The resonator delete is a cost-effective modification for the 2012 Subaru WRX that can yield impressive results. With just a $60 investment, owners can enjoy a more aggressive exhaust sound and a potential 12 horsepower gain. As with any modification, it’s essential to weigh the benefits against the possible downsides, ensuring a satisfying enhancement to your driving experience.
