Installing a HKS Hi-Power exhaust on your GT-R is a popular modification among car enthusiasts. This upgrade not only enhances the sound of your vehicle but also improves its overall performance. In this guide, we will walk you through the installation process and highlight the performance gains you can expect.
Benefits of Upgrading to HKS Hi-Power Exhaust
The HKS Hi-Power exhaust system is designed to provide several advantages over the stock exhaust. Here are some key benefits:
- Improved Performance: The HKS exhaust system reduces back pressure, allowing for better airflow and increased horsepower.
- Enhanced Sound: The exhaust produces a deep, aggressive tone that elevates the driving experience.
- Weight Reduction: The HKS system is lighter than the factory exhaust, contributing to better handling and acceleration.
- Durability: Made from high-quality materials, the HKS exhaust is built to withstand the rigors of performance driving.
Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- HKS Hi-Power Exhaust System
- Socket set
- Wrench set
- Jack and jack stands
- Safety glasses
- Gloves
- Exhaust hanger lubricant
Step-by-Step Installation Guide
Step 1: Prepare Your Vehicle
Begin by parking your GT-R on a flat surface and engaging the parking brake. Use the jack to lift the rear of the car and secure it with jack stands to ensure safety during the installation.
Step 2: Remove the Stock Exhaust
Locate the stock exhaust system and use your socket set to remove the bolts connecting it to the exhaust manifold. Carefully detach the exhaust hangers using a wrench, applying lubricant if necessary to ease the process. Once all connections are loose, remove the stock exhaust from the vehicle.
Step 3: Install the HKS Hi-Power Exhaust
Position the HKS Hi-Power exhaust in place, aligning it with the exhaust manifold. Begin attaching the exhaust using the bolts you removed earlier. Make sure to leave some play in the connections to adjust the alignment later. Secure the exhaust hangers, ensuring they fit snugly.
Step 4: Tighten All Connections
Once the HKS exhaust is properly aligned, use your socket set to tighten all bolts securely. Double-check the exhaust hangers to ensure they are firmly in place. This step is crucial for preventing any leaks or rattling during operation.
Step 5: Lower the Vehicle and Test
Carefully lower your GT-R back to the ground and remove the jack stands. Start the engine and listen for any unusual sounds. The HKS Hi-Power exhaust should produce a deep, aggressive tone. Take your car for a test drive to experience the performance gains firsthand.
Performance Gains and Sound Enhancement
After installing the HKS Hi-Power exhaust, many GT-R owners report noticeable performance improvements. Here are some expected gains:
- Increased Horsepower: The reduction in back pressure allows for improved engine efficiency, resulting in higher horsepower output.
- Better Throttle Response: The enhanced airflow contributes to quicker throttle response, making acceleration more immediate.
- Improved Exhaust Note: The aggressive sound of the HKS exhaust adds to the driving excitement, providing a more engaging experience.
Conclusion
Installing a HKS Hi-Power exhaust on your GT-R is a rewarding modification that enhances both performance and sound. By following the steps outlined in this guide, you can successfully upgrade your exhaust system and enjoy the benefits of improved horsepower and an exhilarating driving experience.
