Preparation Steps
Before beginning the installation, ensure that you have all the necessary tools and materials. It is important to work in a well-ventilated area and to wear safety glasses and gloves for protection.
1. Lift the Vehicle
Using a jack, lift the rear of the vehicle and secure it with jack stands. Make sure the vehicle is stable before proceeding.
2. Remove the Stock Exhaust
Locate the stock exhaust system. Start by removing the bolts connecting the exhaust to the turbo downpipe and the mid-pipe. Use the appropriate socket size and a ratchet to loosen and remove these bolts.

3. Position the New Exhaust
Take the Invidia N1 Cat-back Exhaust system out of the box. Begin by positioning the mid-pipe over the turbo downpipe. Make sure the connection points align properly before securing them.

Once the mid-pipe is in place, attach the exhaust hangers to their respective mounting points on the vehicle. Ensure they are securely fastened and that the exhaust is properly supported.
5. Install the Axle-back Section
Next, install the axle-back section of the exhaust. Align it with the mid-pipe and secure it using the provided bolts. Make sure to tighten the bolts securely but avoid over-tightening.

Once everything is connected, check the alignment of the exhaust system. Ensure that it is not touching any parts of the vehicle and that it is sitting evenly.

7. Torque the Bolts
Using a torque wrench, torque all the bolts to the manufacturer’s specifications. This step is crucial to ensure that the exhaust is properly secured and does not come loose while driving.
8. Lower the Vehicle
After torquing the bolts, carefully lower the vehicle back to the ground using the jack. Remove the jack stands and ensure that everything is clear before driving the car.

Start the engine and listen for any unusual noises. Check for any leaks around the exhaust connections. If everything sounds good, you’re ready to hit the road!
