The Toyota GR86 has garnered attention for its impressive performance and driving experience. One of the most effective upgrades for enhancing its power is installing a new exhaust system. This article will guide you through the process of installing either an Akrapovic or Invidia exhaust system, which can achieve a 10-15 horsepower gain.
Understanding Exhaust Systems
An exhaust system plays a crucial role in a vehicle’s performance by improving airflow and reducing back pressure. Upgrading to a high-performance exhaust system like Akrapovic or Invidia can significantly enhance the GR86’s engine efficiency and power output.
Benefits of Upgrading to Akrapovic or Invidia
- Increased horsepower: Expect a gain of 10-15 HP.
- Improved sound: Both brands offer a sportier, more aggressive exhaust note.
- Weight reduction: High-quality materials reduce overall weight.
- Enhanced aesthetics: Sleek design adds to the vehicle’s appeal.
Tools and Materials Needed
- Socket set
- Wrenches
- Jack and jack stands
- Exhaust hanger removal tool
- New Akrapovic or Invidia exhaust system
- Safety goggles and gloves
Step-by-Step Installation Guide
Step 1: Prepare the Vehicle
Begin by parking the GR86 on a flat surface and engaging the parking brake. Use a jack to lift the vehicle and secure it with jack stands for safety.
Step 2: Remove the Stock Exhaust
Using the socket set, disconnect the bolts securing the stock exhaust system to the headers and mid-pipe. Carefully remove the exhaust hangers using the exhaust hanger removal tool.
Step 3: Install the New Exhaust System
Position the new Akrapovic or Invidia exhaust system in place. Start by attaching the mid-pipe to the headers, ensuring a snug fit. Reinstall the exhaust hangers and secure the bolts with the socket set.
Step 4: Check for Leaks
After installation, start the engine and let it idle. Listen for any unusual noises or leaks around the exhaust connections. If everything sounds normal, proceed to the next step.
Step 5: Lower the Vehicle
Once you’ve confirmed there are no leaks, carefully lower the vehicle back to the ground. Double-check all connections and bolts to ensure everything is secure.
Performance Testing
After the installation, it’s essential to test the performance of your GR86. A dyno test can provide precise measurements of the horsepower gain achieved with the new exhaust system.
Conclusion
Upgrading the exhaust system of your Toyota GR86 to either an Akrapovic or Invidia can yield significant performance benefits. With proper installation, you can achieve a 10-15 horsepower gain, enhancing both the driving experience and the vehicle’s overall performance.
