- Cold Air Intake: $300
- Cat-Back Exhaust System: $800
- Tune: $500
- Headers: $700
- Throttle Body Upgrade: $200
Step-by-Step Installation Guide
Below is a general guide to installing the modifications mentioned above. Always refer to specific instructions for your parts and consult a professional if needed.
1. Install the Cold Air Intake
Begin by removing the factory air intake system. Follow the instructions provided with your cold air intake kit to install the new system, ensuring all connections are secure.
2. Replace the Exhaust System
