Tools and Materials Needed
Before beginning the installation, gather the following tools and materials:

- Socket set
- Wrenches
- Screwdriver set
- Jack and jack stands
- Safety glasses
- Gloves
- Exhaust hanger removal tool (optional)
Step-by-Step Installation Guide
Step 1: Preparation
Before you start the installation, make sure your vehicle is parked on a level surface. Engage the parking brake and wear safety glasses and gloves for protection.
Step 2: Lift the Vehicle
Using a jack, lift the rear of your Lexus IS and secure it with jack stands. This will provide you with enough clearance to work on the exhaust system.
Step 3: Remove the Stock Exhaust System
Start by loosening the bolts that connect the stock exhaust system to the catalytic converter. Use a socket and wrench to carefully remove the bolts. If the exhaust hangers are difficult to remove, an exhaust hanger removal tool can be helpful.
Once the bolts are removed, disconnect the exhaust system from the hangers and carefully take it out from under the vehicle.
Step 4: Prepare the HKS Exhaust System
Unbox your HKS exhaust system and lay out all the components. Familiarize yourself with the parts and ensure you have everything needed for installation.
Step 5: Install the HKS Exhaust System
Begin by positioning the HKS exhaust system under the vehicle. Start by connecting the exhaust to the catalytic converter, ensuring that all flanges align properly. Hand-tighten the bolts to secure it temporarily.
Next, attach the exhaust hangers to their respective mounting points. Ensure that the exhaust is level and properly aligned before tightening all bolts securely.
Step 6: Check for Leaks
Once the installation is complete, start the engine and let it idle for a few minutes. Listen for any unusual sounds and check for exhaust leaks around the connections. If everything sounds good, you’re ready to hit the road!
Final Thoughts
Installing an HKS exhaust system on your Lexus IS can significantly enhance your vehicle’s performance and sound. By following these steps, you can enjoy a more exhilarating driving experience. Always remember to consult with a professional if you’re unsure about any part of the installation process.
