Do I need to use a gasket with this header?

Yes — use a quality header gasket between the header flange and cylinder head. This prevents exhaust leaks and allows for future disassembly if needed.

Will I need to modify my exhaust piping to connect this?

The header outlet diameter and flange position are engineered for K20 swap compatibility, but your existing exhaust piping may require fabrication or adapter work depending on your specific build. Measure your current exhaust diameter before ordering.

Does the ceramic coating affect installation or need curing time?

Ceramic coating is already applied and cured at the factory — ready to bolt on. No prep, curing, or special handling required before installation.
