Exhaust Systems Australia FORD FALCON XR-XF FAIRLANE ZF-ZK 302-351 4V CLEVELAND ## MANDREL BENT ## TRI-Y DESIGN.
Category: Extractors and headers


This Exhaust Systems Australia mandrel-bent Tri-Y header set is listed to fit the Ford Falcon XR to XF and Fairlane ZF, ZK with the 302 and 351 4V Cleveland V8. It replaces the factory manifolds at the engine on these classic Ford V8s, matched to the four-barrel Cleveland head.
A Tri-Y header joins cylinders in two-into-one pairs before merging again, a layout chosen to separate exhaust pulses on a V8. It replaces the cast manifolds with tubular runners that bolt to the heads at the hottest part of the engine bay. Mandrel bending keeps the tube bore consistent through each bend rather than crimping it. It changes the front of the exhaust at the engine, not the system behind it.
Header flanges are cut to a specific port pattern, and the 4V (four-barrel) Cleveland head differs from the 2V version, so this set is listed specifically for the 302 and 351 4V Cleveland used in the XR-XF Falcon and ZF, ZK Fairlane. That distinction is the whole point of the listing: the wrong head pattern will not seal. No power or sound figures are published by the supplier.
It is listed to fit the XR through XF Falcon and ZF, ZK Fairlane with the 302 or 351 4V Cleveland. If your engine runs the 2V head, this is not the matching set, so confirm your head with the workshop before ordering rather than going by the model alone.
Oak Flats Muffler Men fits classic Tri-Y header sets like this in-house across the Illawarra. We confirm the head pattern, seat the flanges, work around steering and chassis clearances on these older Fords, and torque the runners evenly so the joints seal. Supplied by Exhaust Systems Australia at $1,270 AUD; tell us your engine and head and we will confirm the set first.
