Installation Notes

Confirm the vehicle is a 1997-1999 Dodge Dakota before ordering. This part uses pipe connections at both ends and does not include mounting hardware. An exhaust gasket is recommended during installation. Verify local emissions regulations before use, since the fitment notes state it is not legal for sale or use in California and other CARB-compliant states, and it is legal in New York and Maine only on EPA Federal Emission Equipped Vehicles.
