Installation Process
Follow these steps to install the Kohlenstoff downpipe on your B5 S4:
Step 1: Prepare the Vehicle
Start by parking your B5 S4 on a flat surface. Engage the parking brake and disconnect the battery to ensure safety during installation.
Step 2: Raise the Vehicle
Using a jack, lift the front of the car and secure it with jack stands. This will provide easier access to the undercarriage.
Step 3: Remove the Stock Downpipe
Locate the stock downpipe and begin removing the bolts that secure it to the turbo and the exhaust system. Carefully detach the downpipe, making sure to remove any old gaskets.
Step 4: Install the Kohlenstoff Downpipe
Position the Kohlenstoff downpipe in place and secure it using the new bolts and gaskets. Ensure that all connections are tight and properly aligned.
Step 5: Reconnect Everything
Once the downpipe is installed, reconnect any components you removed during the process. This includes the exhaust system and any sensors that may have been detached.
Step 6: Lower the Vehicle and Test
Carefully lower the vehicle back to the ground and reconnect the battery. Start the engine and check for any leaks or unusual noises. Take your B5 S4 for a test drive to experience the enhanced performance.
Considerations After Installation
After installing the Kohlenstoff downpipe, keep the following points in mind:
- Tuning: Consider a tune to maximize the performance gains from your new downpipe.
- Legal Compliance: Check local emissions regulations as downpipes can affect legality.
- Maintenance: Regularly inspect the installation for any signs of wear or leaks.
