The Pacemaker PP4018-01 is a Tri-Y header and full system listed to fit the Ford Falcon XR8 and GT (BA/BF) with the 5.4L Boss V8, as the slug spells out. It pairs tuned-length headers with the complete exhaust behind them.
What does this system cover?
The listing calls it Tri-Y headers and a full system, so it's the extractors plus the complete exhaust that runs behind them — not a tip-only change. On the BA/BF Falcon's 5.4L Boss V8 that means a front-to-back replacement. It's the full-system variant of the PP4018 range, with this one carrying the standard muffler layout.
What's a Tri-Y header and what does it change?
A header swaps the cast manifold for tubular runners; the Tri-Y layout pairs the primaries in stages before merging, which generally favours a fuller mid-range rather than a single peak. As the front of the exhaust it controls how each cylinder clears the head, with the full system behind carrying that flow to the rear. That's the general behaviour of the part type.
Will it suit my Ford Falcon XR8 or GT?
It's listed to fit the BA/BF Falcon XR8 and GT with the 5.4L Boss V8. Confirm your exact variant with the workshop before ordering — fitment is listed to fit rather than guaranteed.
What does fitting involve at our Illawarra workshop?
Pacemaker supplies it; Oak Flats Muffler Men fits the complete header-back system in-house across the Illawarra. With the RRP listed at $3895.62 it's a considered build, so we confirm the spec and book the bay first.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
