Will this bolt directly to my stock exhaust manifold location?

Yes. This header bolts to factory collector points—no drilling or custom mounting brackets needed. Just unbolt the old manifold and bolt this in place.

Do I need to weld this or modify anything under the hood?

No welding required. The bolt-on design connects at the engine using factory attachment points. Check clearance with your downpipe before final installation.

Does this need ceramic coating or paint before I install it?

Stainless steel resists heat discoloration better than mild steel, so coating is optional. If you want a finished look, have it coated before installation—much easier to do off the car.
