The Pacemaker PH4009L_R is a left-and-right competition header set listed to fit the FG Ford Falcon XR8 and GT with the 5.4L 4-valve V8, as the slug names. It replaces the cast factory manifolds with tuned-length tubular headers.
What is a competition header?
A header, or extractor, swaps the cast manifold for tubular runners. The listing calls this the competition header for the FG Falcon — a set the slug flags as competition-oriented. The L_R means it's a left-and-right pair, one for each bank of the 5.4L 4-valve V8, and it sits at the front of the exhaust ahead of everything downstream.
What does the competition label change?
A competition-spec header is generally built for flow over street refinement, which is worth discussing before fitting a registered car. No diameter, material or sound figure is published, so we don't quote any — what's published is the make, model, engine and the competition designation. The workshop can talk through the trade-offs against a street header for the same FG.
Will it suit my Ford Falcon FG?
It's listed to fit the FG Falcon XR8 and GT with the 5.4L 4-valve V8. Confirm your exact variant and how you use the car with the workshop before ordering — fitment is listed to fit, not guaranteed.
What does fitting involve at our Illawarra workshop?
Pacemaker supplies the headers; Oak Flats Muffler Men fits them in the Illawarra. It's a hands-on job — manifolds out, tubular set in, fresh gaskets, and a check of where they tie into the existing system. We confirm the FG build and your intended use before booking the bay.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
