- Enhanced Sound: Upgrading to HKS downpipes provides a more aggressive exhaust note, enhancing the overall driving experience.
Gathering Necessary Tools and Parts
Before starting the installation, ensure you have the following tools and parts ready:
- Tools Required:
- Socket set
- Torque wrench
- Jack and jack stands
- Wrenches
- Cutting tool (if necessary)
- Parts Required:
- HKS downpipes
- New gaskets
- Cobb tuning accessport
Step-by-Step Installation of HKS Downpipes
Follow these steps to install the HKS downpipes on your B58 engine:
- Step 1: Safely lift the vehicle using a jack and secure it with jack stands.
- Step 2: Remove the undertray to access the exhaust system.
