Step-by-Step Installation Guide
Step 1: Prepare Your Vehicle
Start by parking your E46 330i on a flat surface and ensuring the engine is cool. Use a jack to lift the car and secure it with jack stands. Always wear safety glasses and gloves during the installation process.

Step 3: Install the Performance Exhaust
With the stock exhaust removed, position the new performance exhaust in place. Align it with the headers and the hangers. Secure the exhaust using the provided bolts and ensure everything is tightened to the manufacturer’s specifications using a torque wrench.
Step 4: Check for Leaks
After installation, start the engine and let it idle. Listen for any unusual sounds that may indicate exhaust leaks. If you hear any, double-check your connections and tighten them as necessary.
Step 5: Lower Your Vehicle
Once you are satisfied with the installation and there are no leaks, carefully lower your vehicle back to the ground. Ensure all tools are removed from under the car.
