Debating Heat Dispersion Cast Iron vs. Steel Exhaust Systems

[Gregory]

Striking the right balance in between performance, durability, and cost is crucial when selecting materials for exhaust systems. 1 aspect to contemplate is the thermal expansion coefficient of the material, which affects its response to temperature changes. Cast iron typically has a lower coefficient of thermal expansion in comparison to steel, which can reduce the risk of exhaust leaks and fatigue cracking. However, steel alloys can be engineered to withstand thermal cycling and high temperatures, generating them suitable for performance-oriented applications. How do you navigate these trade-offs in material selection?
