Preparation Steps
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all necessary tools and materials to make the process smoother.
1. Safety First
Wear safety glasses and gloves throughout the installation to protect yourself from debris and sharp edges. Make sure to work in a well-ventilated area.

Use a jack to lift the rear of the vehicle. Secure it with jack stands to ensure safety while working underneath the car.
Removing the Stock Exhaust
To install the HKS exhaust, you must first remove the stock exhaust system. Follow these steps carefully.
1. Disconnect the Exhaust Hangars
Locate the exhaust hangars and carefully disconnect them using a socket wrench. This will allow you to remove the exhaust system without damaging the hangars.
2. Remove the Exhaust Bolts
Using a socket wrench, remove the bolts connecting the exhaust to the headers and mid-pipe. Keep these bolts as you may need them for the new exhaust.
3. Take Out the Stock Exhaust
Carefully slide the stock exhaust out from under the vehicle. If it’s stuck, gently twist and pull to release it from the hangars.

1. Position the New Exhaust
Align the HKS exhaust system with the exhaust hangars and mid-pipe. Make sure it fits properly before securing it.
2. Secure the Exhaust
Using the original bolts, secure the exhaust to the headers and mid-pipe. Make sure to apply anti-seize lubricant to the threads for easier removal in the future.
3. Reattach the Exhaust Hangars
Reconnect the exhaust hangars to ensure the exhaust is securely held in place. Double-check that everything is aligned properly.
Final Steps
After installing the HKS Super Turbo Exhaust, it’s essential to check your work and ensure everything is functioning correctly.
