Preparation Before Installation
Before you begin the installation, ensure that you have all the necessary tools and materials. It’s also important to work in a well-ventilated area and wear safety gear to protect yourself during the process.
Step 1: Lift the Vehicle
Start by lifting the vehicle using a jack. Secure it with jack stands to ensure it is stable while you work underneath.
Step 2: Remove the Undertray
Remove the undertray from the bottom of the vehicle by unscrewing the bolts holding it in place. This will give you access to the exhaust system.
Step 3: Disconnect the Battery
For safety, disconnect the negative terminal of the battery to prevent any electrical issues during the installation.
Removing the Stock Headers
Step 4: Remove the Exhaust System
Begin by loosening the clamps on the exhaust system and then disconnecting it from the stock headers. You may need to remove additional components to gain full access.
Step 5: Unbolt the Stock Headers
Using your socket set, unbolt the stock headers from the engine. Be careful not to drop any bolts into the engine bay.
Step 6: Remove the Old Gaskets
Remove the old gaskets from the engine and the exhaust ports. Ensure that the surfaces are clean and free of debris.

Step 7: Apply Anti-Seize Compound
Before installing the new headers, apply a high-temperature anti-seize compound to the threads of the bolts to prevent them from seizing in the future.
Step 8: Position the New Headers
Carefully position the ARH headers onto the engine. Make sure they align properly with the exhaust ports.
Step 9: Bolt the Headers in Place
Using your torque wrench, bolt the headers in place according to the manufacturer’s specifications. Ensure that the bolts are tightened evenly to prevent warping.
Step 10: Install New Gaskets
If necessary, install new gaskets between the headers and the exhaust system to create a proper seal.
Reassembling the Exhaust System
Step 11: Reconnect the Exhaust System
Reconnect the exhaust system to the new headers and secure it with clamps. Ensure all connections are tight to prevent leaks.
Step 12: Reinstall the Undertray
Once the exhaust system is securely connected, reinstall the undertray and tighten all bolts.
Final Steps
Step 13: Reconnect the Battery
Reconnect the negative terminal of the battery. Ensure that all connections are secure.
Step 14: Start the Engine
Start the engine and listen for any unusual sounds. Check for leaks around the headers and exhaust connections.
Step 15: Test Drive
Take your vehicle for a test drive to ensure everything is functioning properly. Pay attention to the performance and sound of the engine.
