- Axle-Back Exhaust: This option replaces the rear section of the exhaust system, enhancing sound without affecting the catalytic converter or mid-pipes. It typically produces a deeper, more aggressive sound while maintaining a relatively easy installation process, making it a popular choice for those desiring an improved audio experience without extensive modifications.
- Cat-Back Exhaust: A cat-back system replaces the exhaust system from the catalytic converter to the rear of the vehicle. This type often results in a significant boost in sound volume and quality, providing a more pronounced growl and performance increase while improving exhaust flow, which can lead to better engine efficiency.
- Headers: Upgrading to aftermarket headers can dramatically change the sound profile of the ATS-V. By allowing exhaust gases to exit the engine more efficiently, headers not only enhance overall performance but also contribute to a throatier sound, making the vehicle more exhilarating to drive.
- Valved Exhaust: This system incorporates adjustable valves that can change the exhaust flow and sound on demand. It allows drivers to switch between a quieter, more subdued sound for daily driving and a loud, aggressive tone for spirited driving, providing versatility based on driving conditions and personal preference.
What Prices Should You Expect for ATS-V Exhaust Systems?
- Cat-Back Exhaust Systems: These systems can range from $1,000 to $2,500, depending on the manufacturer and the materials used. Cat-back systems replace the exhaust from the catalytic converter back, improving airflow and enhancing sound, which can lead to increased performance.
