The Pacemaker PP4496-01 is a header-back full twin 2-1/2in system with cat, listed to fit the Ford Falcon XR6 sedan (BA-BF-FG) with the 4.0L Barra. It runs from the headers all the way back as a twin layout and keeps the catalytic converter.
What does this system cover?
PP4496-01 is a header-back run: headers off the 4.0L Barra six, then a full twin 2-1/2in system to the rear, with the catalytic converter retained. "Header-back" means it replaces the exhaust from the manifold flange rearward, and "twin" means two pipes share the run rather than a single bore. At 2-1/2in across two pipes it's sized for the Barra, and as a full kit the header, cat and pipework are matched for the XR6 sedan.
What's a header-back twin system and what does it change?
A header-back system spans from the headers to the tailpipe — a longer change than a cat-back. The twin layout splits the flow across two 2-1/2in pipes, which is a packaging and flow choice rather than a single large bore. With the cat retained, the emissions hardware stays in the line. We publish no power or sound figures, so we describe it honestly as a header-back full twin 2-1/2in system with cat — a full-system change in character, not a measured gain.
Is it road legal?
This system keeps the catalytic converter, so the emissions equipment the Falcon carries stays in place. That's the usual sticking point for road compliance, and retaining the cat addresses it — but compliance also depends on your state's requirements and how the car is presented, so confirm the exact build and any NSW requirements with the workshop before fitting.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits header-back systems like this in-house across the Illawarra. We fit the headers at the Barra's head, install the cat, then hang and align the twin 2-1/2in pipework back to the rear of the XR6 sedan. It's listed to fit the BA-BF-FG XR6 sedan; send your build and we'll confirm clearances and book the bay. Recommended retail is $2,130.21.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Does the PP4496-01 keep the catalytic converter?
- Yes — it's a with-cat system, so the catalytic converter stays in the line rather than being deleted.
- Is it a single or twin system?
- Twin. It runs a full twin 2-1/2in layout from the headers back, rather than a single-pipe system.
- Will it fit my Falcon XR6?
- It's listed to fit the Ford Falcon XR6 sedan across BA-BF-FG with the 4.0L Barra. Confirm your exact variant with the workshop before ordering.
