Exhaust Material Options
Aluminized Steel (Most Popular)
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 is not stainless. Built to withstand heat, moisture, and vibration while offering improved long-term durability.
