Preparation
Before you begin the installation, ensure that your vehicle is parked on a flat surface and that the engine is cool. Gather all the tools and materials listed above to streamline the process.
Step 1: Raise the Vehicle
Using a jack, lift the rear of the vehicle and secure it with jack stands. Ensure the vehicle is stable before proceeding.
Step 2: Remove the Old Exhaust
Start by applying lubricant to the exhaust hangers to make removal easier. Use the exhaust hanger removal tool to detach the hangers from the old exhaust system.
Next, locate the bolts securing the exhaust to the turbo and the rear section. Use your socket set to remove these bolts carefully. Once all bolts and hangers are removed, gently lower the old exhaust from the vehicle.
Step 3: Prepare the Milltek Exhaust
Unbox the Milltek cat-back exhaust system and lay out all components. Ensure you have all parts according to the installation manual. Familiarize yourself with how the system will fit together.
Step 4: Install the Milltek Exhaust
Begin by positioning the new exhaust under the vehicle. Start with the front section, aligning it with the turbo outlet. Secure it using the provided bolts, ensuring a tight fit.
Next, attach the mid-section of the exhaust, again securing it with bolts. Ensure all connections are tight and that the exhaust is properly aligned.
Finally, attach the rear section of the exhaust to the mid-section. Use the exhaust hangers to secure the system in place. Make sure everything is aligned properly to avoid any rattling or misalignment.
Step 5: Final Checks
Once the Milltek exhaust is installed, double-check all bolts and hangers to ensure everything is secure. Lower the vehicle back to the ground and remove the jack stands.
Step 6: Test Drive
Start the engine and let it idle for a few minutes. Listen for any unusual noises that may indicate a loose connection. Once satisfied, take the vehicle for a test drive to experience the performance boost.
Conclusion
Installing a Milltek cat-back exhaust on your Mk1 TT 1.8T is a rewarding project that can enhance your vehicle’s performance by up to 15 horsepower. By following this step-by-step guide, you can ensure a successful installation and enjoy the benefits of improved exhaust flow and sound.
