Will these headers bolt directly to my engine without cutting or drilling?

These mount at factory exhaust manifold points — no engine bay modifications needed. Verify collector outlet diameter matches your downpipe before final assembly.

Do I need to paint or coat these headers after installation?

Stainless steel resists discoloration from heat, but bare metal can develop surface patina over time. Many builders coat them with high-temp ceramic or polishing compound for appearance — either route works functionally.

What gaskets or hardware do I need to seal the header flanges?

Header gaskets and mounting hardware are not included — source gaskets rated for your engine's port size and fasteners compatible with your engine block bolt pattern. Check your service manual for torque specs.
