Deleting the centre muffler is the whole point of the Pacemaker PP4007-02: it's a cat-back system for the Ford Falcon XR8 FG (5.4L Boss) that runs without a centre muffler and finishes in a dual outlet, so the note opens up compared with the restrictive factory mid-section.
What does the centre-muffler delete change?
Pulling the centre muffler out of the cat-back path removes one of the two damping stages the factory used to keep the 5.4L Boss V8 subdued. The PP4007-02 keeps the rear silencing and routes to a dual outlet, so the result is a freer mid-section and a fuller, harder note than stock — louder than the standard car, without going to a fully straight-through tailpipe.
What's a cat-back and where does it sit?
A cat-back replaces the exhaust from behind the catalytic converter rearward — the pipes, any centre and rear mufflers, and the tailpipes — while leaving the engine-side hardware and converters alone. It's the section a workshop changes to alter flow and sound on a road car without touching the emissions equipment up front.
Will it suit my XR8 FG?
This Pacemaker system is listed to fit the Ford Falcon XR8 FG with the 5.4L Boss V8. Falcon FG running gear varies across the range, so send your exact build to Oak Flats Muffler Men and we'll confirm the fitment before ordering.
What does fitting involve at our Illawarra workshop?
We fit cat-back systems like the PP4007-02 in-house at Oak Flats in the Illawarra. The job covers offering the system up to the factory mounting points, checking clearances over the rear subframe and tank, and setting the dual outlet sit before final tightening. Road-compliance specifics aren't published with the part, so confirm registration requirements with us as part of the booking.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
