Pacemaker PH 4018 Falcon BA-BF 5.4L 4 Valve Tri-Y.
Category: Extractors and headers


The Pacemaker PH4018L_R is a tri-Y extractor set listed to fit the Ford Falcon BA/BF with the 5.4L 4-valve V8. It's a left- and right-hand pair of headers that replaces the cast factory exhaust manifolds on the engine.
Extractors — headers — bolt to the cylinder heads in place of the restrictive cast manifolds the Falcon left the factory with. A tri-Y design pairs the primary pipes in stages before they merge, a layout chosen on V8s to tune scavenging across the rev range rather than chase one peak. On the 5.4L 4-valve they're the first step in an exhaust build, sitting ahead of any cats, pipework or mufflers further back. We publish no flow, power or sound figures for this set, and we won't invent any.
It's listed to fit the BA/BF Falcon with the 5.4L 4-valve V8. The L_R suffix means you get matched left and right headers for the engine. Falcons of this era vary by body and accessories, so the cleanest path is to confirm your exact build with the workshop against the listing before ordering.
These are extractors, not a catalytic converter or muffler, so they don't carry an emissions approval of their own. Whether the finished exhaust meets NSW road requirements depends on what's fitted behind them and how the system is engineered. No compliance approval is published by the supplier, and we won't claim one.
Oak Flats Muffler Men fits Falcon extractors like the PH4018L_R in-house across the Illawarra. We check clearance against steering and chassis, fit fresh gaskets, and seal the joints before tying them into the rest of the system. We match the listing to your 5.4L Falcon first. RRP is listed at 1235.69 AUD; fitting is quoted once we've seen the vehicle.
