The Subaru Outback is known for its versatility and reliability, but many enthusiasts seek to enhance its performance. One popular modification is the resonator delete, which can potentially increase horsepower and improve exhaust sound. In this article, we will explore the cost, installation process, and expected horsepower gains from a DIY resonator delete on a Subaru Outback.
What is a Resonator Delete?
A resonator delete involves removing the resonator from the exhaust system. The resonator is designed to reduce noise and modify sound frequencies. By removing it, the exhaust system becomes less restrictive, which can lead to a more aggressive sound and slight performance gains.
Benefits of a Resonator Delete
- Increased horsepower: Many Subaru Outback owners report gains of 8-10 HP.
- Improved exhaust sound: A more aggressive and sporty exhaust note.
- Reduced weight: Removing the resonator can decrease the overall weight of the exhaust system.
- Cost-effective modification: Generally inexpensive compared to other performance upgrades.
Cost of a Resonator Delete
The cost of a resonator delete can vary based on whether you choose to do it yourself or hire a professional. Here are some estimated costs:
- DIY Cost: $50 – $150 for materials (pipe, clamps, etc.).
- Professional Installation: $100 – $300, including labor.
Installation Process
Installing a resonator delete on your Subaru Outback can be a straightforward process if you have basic mechanical skills. Here’s a step-by-step guide:
Tools and Materials Needed
- Socket set
- Wrench set
- Jack and jack stands
- Pipe cutter or sawzall
- Replacement pipe (specific to your Outback model)
- Exhaust clamps
- Safety glasses and gloves
Step-by-Step Installation
- 1. Prepare the Vehicle: Park the Outback on a flat surface, engage the parking brake, and lift the rear of the car using a jack and jack stands.
- 2. Locate the Resonator: Identify the resonator in the exhaust system; it is typically located between the catalytic converter and the muffler.
- 3. Remove the Old Resonator: Use a socket set to unbolt the resonator from the exhaust pipes. If necessary, cut the resonator out using a pipe cutter or sawzall.
- 4. Install the Replacement Pipe: Fit the new pipe in place where the resonator was removed. Ensure it fits snugly and aligns with the existing exhaust system.
- 5. Secure the New Pipe: Use exhaust clamps to secure the new pipe in place. Make sure everything is tight to prevent leaks.
- 6. Lower the Vehicle: Carefully lower the Outback back to the ground.
- 7. Test the Exhaust: Start the engine and listen for any unusual sounds or leaks. Ensure the exhaust flows freely.
Expected Horsepower Gains
After completing the resonator delete, many Subaru Outback owners report an increase in horsepower. While individual results may vary, you can generally expect gains of:
- 8-10 HP: This is a common range reported by users.
- Improved throttle response: A less restrictive exhaust can enhance overall engine responsiveness.
Conclusion
A DIY resonator delete on a Subaru Outback is a cost-effective way to enhance performance and sound. With the right tools and a bit of mechanical knowledge, this modification can be completed in a few hours. Enjoy the benefits of increased horsepower and a more aggressive exhaust note!
