Exhaust Material Options
Aluminized Steel
A cost-effective performance option offering excellent strength and heat resistance. Aluminized steel may develop surface rust over time, especially in harsh or wet environments.
T409 Stainless Steel
Recommended for trucks that see winter driving or salted roads. T409 stainless is magnetic by nature—this is normal and does not mean it isn’t stainless. Built to handle heat, moisture, and abuse while delivering long-term durability.
