    Uses Trans Dapt collector gaskets 969-4465 or 969-9864.
    Trans Dapt Exhaust Header Reducers are a must when updating your exhaust system or just simply adding or replacing a set of headers. These header reducers are made from heavy gauge aluminized tubing and designed for headers with a 3-bolt triangular flange.
    Trans Dapt Header Collector Gaskets will keep all exhaust gases flowing through your headers, not around the flange, for a leak proof seal. Each header collector gasket is made of the same white high-temperature material that is included with each set of new Hedman Hedders. These gaskets are available in your choice of 1/16 inch or 1/8 inch thicknesses. .
