Hedman's 3-Bolt flange hedder reducers are for use with Hedman Hedders fitted with 3-bolt gasketed collectors. Many of Hedman's newer hedder models utilize a ball & socket style collector. If your Hedman Hedders have this style of collector they do not require a gasket. Mild steel. These reducers have built-in O2 sensor bungs. SOLD INDIVIDUALLY.
