PH 4496 Competition Header 4L Twin Cam Barra BA-FG Falcon.
Category: Extractors and headers


The Pacemaker PH4496 Falcon kit (MPN PH4496_KIT_-_FALCON) is a competition header for the 4L twin-cam Barra six, listed to fit the Ford Falcon BA to FG. It's a header kit built for the inline Barra.
This is a competition-grade header for the 4L twin-cam Barra inline six, supplied as a kit and listed for the Ford Falcon BA through FG. Pacemaker labels it a competition header, which signals it's aimed at performance use rather than a stock replacement. On a Barra — the engine Falcon owners build hard — the header is the front of the exhaust, so the rest of the system is matched behind it. No diameter, flow or power figures are published by the supplier.
Headers (extractors) replace the cast factory manifold with tubular primaries that give each cylinder a tuned path out. On a turbo or built Barra they're a common early step because the standard manifold is a known restriction. As a competition kit this set is oriented toward performance use, so where and how it's run matters. What it delivers depends on the rest of the exhaust and the tune — we publish no numbers and won't quote any.
It's listed to fit the Ford Falcon BA to FG with the 4L twin-cam Barra. That BA-FG span and the Barra engine are the defining details, so confirm your exact model and engine with the workshop before ordering — and note this is the Falcon kit, distinct from the Territory version in the same family.
Oak Flats Muffler Men fits Barra competition headers in the Illawarra. We check primary clearance, fit fresh gaskets, and plan the system from the collector back. Because it's a competition header, we'll confirm how the car is used and built first. RRP is listed at 843 AUD; fitting is quoted once we've seen the car.
