Shipping

• FREE Ground Shipping
• Typical delivery time: 4–7 business days

Exhaust Material

• Aluminized steel. 
• T409 Stainless Steel Construction

T409 stainless is specifically chosen for exhaust applications due to its strength and resistance to heat and corrosion. Unlike T304 stainless, T409 is magnetic by nature—this is completely normal and does not mean the material is not stainless.

For trucks that see winter driving or salted roads, T409 stainless is strongly recommended for long-term durability.

Installation

• Approximate install time: ~2-4 hours with basic hand tools
• Can be installed in a driveway or garage (faster with an automotive lift)
• Cutting may be required for certain cab/bed or shorter wheelbase configurations
• Clamps, hangers, and hardware included
• Some factory hardware may need to be reused

Designed for a clean, straightforward install—no unnecessary complications.
