When to replace it

Exhaust donut gaskets crush when tightened and should not be reused. Fit a new one whenever the downpipe, cat or manifold is removed, or if you hear blowing at the front of the exhaust. Order the Honda EP3 Donut Gasket by its Honda part number 18229-S6M-A51 to be sure of the correct item.
