How Do Different Materials Impact Exhaust Performance and Sound?

Different materials significantly influence exhaust performance and sound characteristics.

  • Stainless Steel: Stainless steel is widely favored for its durability and corrosion resistance, making it ideal for exhaust systems in various weather conditions. It provides a balanced sound that can range from deep and throaty to a more refined tone, depending on the design.
