Will these bolt directly to my stock intake and exhaust?

The collector threads into factory-style mounting points, but verify your vehicle's specific intake flange and exhaust outlet configuration before ordering. Some manifold adapters or gaskets may be needed depending on your setup.

Do I need to remove or modify anything under the hood to install these?

Long tube headers typically require clearance for the primary tubes. Check fitment around steering components, belts, and suspension before committing to installation. Some vehicles need minor heat shielding or bracket relocation.

What gaskets or fasteners come with the headers?

Header assembly only — bring your own intake gaskets, exhaust gaskets, and mounting hardware. Have your intake manifold gasket and header-to-exhaust gasket on hand before you start.
