Installing a Turbosmart 2.75-inch downpipe on your Subaru STI can significantly enhance performance and sound. However, to achieve the best results, it’s essential to follow best practices during the installation process. This article provides a comprehensive guide to ensure a successful installation.
Preparation Before Installation
Before diving into the installation, proper preparation is key. Gather all necessary tools and parts to streamline the process.
- Socket set

Step-by-Step Installation Process
Step 1: Raise the Vehicle
Using a jack, raise the vehicle and secure it with jack stands. Ensure the vehicle is stable before proceeding.
Step 2: Remove the Stock Downpipe
Locate the stock downpipe and remove any heat shields if necessary. Unbolt the downpipe from the turbo and the mid-pipe. Carefully detach it from the vehicle.
Step 3: Install the New Turbosmart Downpipe
Position the Turbosmart downpipe in place. Ensure it aligns correctly with the turbo and mid-pipe. Use new gaskets to prevent leaks.
Step 4: Secure the Downpipe
Tighten the bolts using a torque wrench to the manufacturer’s specifications. This step is crucial to avoid any exhaust leaks.
Step 5: Reattach Heat Shields
If you removed any heat shields, reattach them to protect the downpipe and surrounding components from heat damage.
Post-Installation Checks
After installing the downpipe, conduct several checks to ensure everything is in order.
- Check for any visible leaks around the downpipe.
- Ensure all bolts are tightened to specification.
- Inspect surrounding components for any signs of contact.
Testing Your Installation
Once the installation is complete, start your vehicle and let it idle for a few minutes. Listen for any unusual noises or leaks. Take the car for a test drive to assess performance and sound.
Common Troubleshooting Tips
If you encounter issues post-installation, consider the following troubleshooting tips:
- Check for loose bolts if you hear rattling noises.
- Inspect gaskets for leaks if you notice exhaust fumes.
- Ensure proper alignment of the downpipe with other exhaust components.
