Exhaust Material

• Built from T-409 Stainless Steel for strength and corrosion resistance

• Approx. 1-hour install with basic hand tools (faster with a lift)
• May require minor cutting for shorter wheelbase setups
• Includes clamps, hangers, and hardware (some factory hardware reused)

Performance Benefits

• Fuel Mileage Gains – Expect up to 18–19 MPG combined after deleting DPF/CAT (driving habits and larger tires may affect results)
