The Pacemaker PP4018-03 is a Tri-Y header and full system with a dual outlet, listed to fit the Ford Falcon GT (BF) 5.4L Boss V8, as the slug describes. It pairs tuned-length headers with the complete twin-exit exhaust.
What does this system cover?
The listing names Tri-Y headers and a full system in a dual-outlet configuration (the slug's "duel outlet"). So it's the extractors plus the complete exhaust behind them, finishing through two exits rather than one. On the BF Falcon GT's 5.4L Boss V8 that's a full front-to-back change with a twin tailpipe layout.
What's a Tri-Y header and what does it change?
A header swaps the cast manifold for tubular runners; the Tri-Y arrangement pairs the primaries in stages, generally favouring a fuller mid-range. It sits at the front of the exhaust and sets how each cylinder clears the head, while the full dual-outlet system carries that flow to two rear exits. That's the general behaviour of the part type.
Will it suit my Ford Falcon GT?
It's listed to fit the BF Falcon GT with the 5.4L Boss V8. Confirm your exact variant with the workshop before ordering — fitment is listed to fit, not guaranteed, and rear-bar clearance for a dual outlet is worth checking on the car.
What does fitting involve at our Illawarra workshop?
Pacemaker supplies it; Oak Flats Muffler Men fits the full dual-outlet system in-house across the Illawarra. At a listed $4537.21 it's a considered build, so we confirm the spec and the rear-exit fit before booking the bay.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
