PH 4007 Falcon XR8 & GT FG 5.4L 4 Valve.
Category: Extractors and headers


The Pacemaker PH4007L_R is a left-and-right extractor set listed to fit the Ford Falcon XR8 and GT (FG) with the 5.4L 4-valve V8, as the slug names. It replaces the cast factory manifolds with tuned-length headers.
Headers, or extractors, swap the cast-iron manifolds for tubular runners. The L_R in the part number means a left-and-right pair, one for each bank of the FG Falcon's 5.4L 4-valve V8. They sit at the front of the exhaust and govern how cleanly each cylinder clears the head; the rest of the system bolts on behind them.
The listing ties this set to the FG Falcon XR8 and GT with the 5.4-litre four-valve V8 — the quad-cam Boss family of that era. No diameter, material or sound figure is published for this set, so we don't quote any; what's confirmed is the make, model and engine the listing names, with the rest checked on the car.
It's listed to fit the FG Falcon XR8 and GT with the 5.4L 4-valve V8. Confirm your exact variant with the workshop before ordering — fitment is listed to fit, not guaranteed.
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 book the bay once your FG build is confirmed.
