Do these bolt directly to the factory mounting points?

Yes. These mount at the factory engine block locations — no drilling or fabrication required. You'll need to verify any gaskets or fasteners are compatible with your vehicle's service manual specs.

Will I need a tune or ECU adjustment after install?

Not necessarily, but adding headers alone can trigger a check engine light if your oxygen sensor wiring shifts during install. Route wires carefully and monitor your dash after startup. A tune is optional and depends on your other modifications.

Does this header require ceramic or heat wrap coating?

Not required. Stainless steel naturally resists corrosion and heat damage. Heat wrap is optional if you want to reduce underhood temperatures or protect adjacent components — that choice is yours based on your setup.
