Ford Falcon XR8-GT BA -BF 5.4L Boss Cat Back System - No Centre Muffler (SKU: PP4008-02), $1490.42 from Pacemaker.
Category: Mufflers and resonators


Built for the earlier BA/BF Falcons, the Pacemaker PP4008-02 is a cat-back system for the Ford Falcon XR8 and GT (BA/BF, 5.4L Boss) that runs without a centre muffler — the centre-delete that frees up the mid-section over the factory layout.
The factory BA/BF cat-back used a centre muffler as part of keeping the 5.4L Boss V8 quiet. The PP4008-02 deletes it, so the mid-section flows more freely and the note opens up to a fuller, harder character than stock — louder than standard, with the rear silencing still doing the bulk of the work.
This is the BA/BF-era system, listed to fit the Ford Falcon XR8 and GT with the 5.4L Boss V8. Those generations span several model years and trims, so confirm your exact BA or BF build with Oak Flats Muffler Men before ordering.
A cat-back replaces the exhaust behind the catalytic converters — mid-pipes, mufflers and tailpipes — and leaves the converters and engine-side hardware in place. It's how a road car's flow and sound are changed without touching the front-end emissions equipment.
Oak Flats Muffler Men fits this centre-delete cat-back in-house in the Illawarra, offering it up to the factory BA/BF mounts, routing the centre-delete mid-section and checking clearance over the rear subframe and tank before final tightening. Road-compliance detail isn't supplied with the part, so confirm registration requirements with us.
