Tools and Materials Needed
- Milltek Sport downpipes
- Socket set
- Torque wrench
- Jack and jack stands
- Safety glasses
- Gloves
- Exhaust gasket (if necessary)
- Penetrating oil
Preparation
Before starting the installation, ensure that your vehicle is parked on a level surface. Engage the parking brake and allow the exhaust system to cool down completely.
Step 1: Lift the Vehicle
Using a jack, lift the front of the vehicle and secure it with jack stands. Ensure the vehicle is stable before proceeding.
Step 2: Remove the Undertray
Remove the undertray by unscrewing the bolts holding it in place. This will provide access to the exhaust system.
Removing the Stock Downpipes
Step 3: Disconnect the Exhaust
Locate the connection points of the stock downpipes to the rest of the exhaust system. Use a socket set to disconnect the bolts. Apply penetrating oil if the bolts are rusted.
Step 4: Remove the Downpipes
Once disconnected, carefully remove the stock downpipes from the vehicle. You may need to maneuver them to clear any obstacles.

Step 5: Prepare the New Downpipes
Before installation, inspect the Milltek Sport downpipes for any damage. Ensure that all necessary gaskets are included.
Step 6: Install the New Downpipes
Position the Milltek Sport downpipes in place and align them with the exhaust system. Secure them using the provided bolts. Ensure a snug fit but do not overtighten at this stage.
Finalizing the Installation
Step 7: Reconnect the Exhaust
Reconnect the rest of the exhaust system to the new downpipes. Tighten the bolts to the manufacturer’s specifications using a torque wrench.
Step 8: Reinstall the Undertray
Once everything is secured, reinstall the undertray by screwing it back into place. Ensure all screws are tightened properly.
Testing the Installation
With everything installed, lower the vehicle back to the ground. Start the engine and listen for any unusual sounds. Check for leaks around the connections.
