01-05 Honda Civic Aluminum Exhaust Header Gasket

Do I need to buy more than one gasket for my header swap?

Check your header design—single-plane and log-style headers typically use one gasket at the manifold junction, but verify your specific header's port count and mounting configuration before ordering.

Can I reuse my old gasket or does this need to be fresh every time?

Exhaust gaskets compress and harden after heat cycling. Once disturbed, install fresh aluminum gaskets to ensure a clean seal and prevent exhaust leaks at the joint.

What hardware do I need to bolt this down?

Fasteners are not included. Use your header's stock bolt kit or OEM manifold bolts—confirm bolt size and thread pitch with your header manufacturer's spec sheet before assembly.
