Will these fit my engine without custom fabrication?

These mount at factory engine points, so you won't need frame or suspension work. Verify your specific engine displacement and block type before ordering — clearance between the headers and firewall varies by year and engine combination.

Do these headers come with gaskets and bolts?

The header assembly is included. You'll need to source your own gaskets, bolts, and flanges to match your engine block — these are commonly available at any automotive supply shop.

Can I run these as-is or do they need ceramic coating?

Stainless steel resists oxidation naturally, so coating is optional. If you want heat reduction under the hood or aesthetic finishing, ceramic coating can be applied after installation — prep and cure time will depend on the coating product you choose.
