Benefits of a Performance Exhaust System
Upgrading to a performance exhaust system offers several advantages:
- Improved Sound: A performance exhaust enhances the engine’s sound, providing a deeper and more aggressive tone.
- Increased Power: By reducing back pressure, a performance exhaust can lead to noticeable gains in horsepower and torque.
