The Pacemaker PP4008-04 is the middle-ground cat-back for the Ford Falcon GT BF (5.4L Boss): centre muffler deleted for a freer mid-section, but twin rear mufflers and a quad-tip outlet retained, so it's louder than stock while keeping rear silencing.
Why delete the centre and keep the rear pair?
Pulling the centre muffler opens the cat-back's mid-section so the 5.4L Boss V8 finds more voice, while the two rear mufflers stop it tipping into a fully raw straight-through note. The quad-tip outlet finishes the look. It's the balance build between the fully silenced and the stripped layouts in this BF family.
What does a cat-back cover?
A cat-back is the exhaust from behind the catalytic converters to the tips — mid-pipes, mufflers and tailpipes — leaving converters and engine-side hardware in place. It's the part changed to tune road-car flow and sound without touching front-end emissions equipment.
Will it suit my Falcon GT BF?
The PP4008-04 is listed to fit the Ford Falcon GT BF with the 5.4L Boss V8. BF builds differ, so send yours to Oak Flats Muffler Men and we'll confirm the fitment before you order.
What does fitting involve in the Illawarra?
Our Oak Flats workshop fits this from the converter flanges back, routing the centre-delete mid-pipe, hanging both rear mufflers and aligning the quad tips evenly in the valance. We check tank and subframe clearance and set tip sit before final tightening. Compliance specifics aren't supplied with the part — confirm registration requirements with us.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
