The sound of each exhaust system for the GT350 can vary significantly based on design, materials, and intended performance characteristics.
- Stock Exhaust System: The factory exhaust system is designed to provide a balanced sound profile that complements the GT350’s naturally aspirated V8 engine.
- Axle-Back Exhaust System: This system replaces the rear portion of the exhaust, enhancing sound without altering exhaust flow significantly, resulting in a more aggressive tone.
