Do these bolt directly to the factory exhaust manifold mounting points?

Yes, they mount at factory locations with no drilling or modifications required. You'll connect them to your existing exhaust piping downstream.

Will I need new gaskets and fasteners to install these?

Have new header gaskets ready before install — factory ones are single-use. Bring your existing hardware to verify compatibility, or source new mounting bolts if originals are stripped or damaged.

What prep work does the stainless steel need before bolting on?

These ship ready to install. No painting or coating required. Wipe down with a clean cloth before mounting to remove any manufacturing residue.
