Holden Commodore VE VF V8 Ute & WM/WN Caprice Dual 2.5in Full System 1 7/8in HPC Extractors.
Category: Extractors and headers


The MPI Automotive HOLK128U25-178C is a set of ceramic-coated 1-7/8in extractors built around a dual 2.5in full system, listed to fit the Holden Commodore VE-VF V8 Ute (and the WM-WN Caprice). It's the front-of-system header swap for the LS-era V8, finished with a high-performance ceramic coating.
Extractors (also called headers) replace the factory exhaust manifolds — the cast pieces that collect spent gas straight off the cylinder head. On a V8 like this Commodore's, a primary pipe runs from each port before merging into a collector, which is where the long 1-7/8in primaries on this set come in. The trade-off is real: tubular extractors can free up exhaust flow over a cast manifold, but they sit in a tight engine bay, run closer to ancillaries, and need careful fitment. This set is matched to a dual 2.5in full system, so it's designed to flow as one package from the head back rather than as a bolt-on in isolation.
The "178C" in the HOLK128U25-178C marks the ceramic (HPC-style) coating on the 1-7/8in primaries. A coating like this is applied to header tubes to manage surface heat and corrosion; the supplier hasn't published a temperature or finish-life figure, so we won't quote one. What it changes versus the uncoated version in this range is the finish on the steel, not the 2.5in pipe sizing or the V8 fitment.
It's listed to fit the Holden Commodore VE-VF V8 in Ute form, and the same listing covers the WM-WN Caprice. Because the years aren't published in our record, and Commodore V8 builds vary across that run, confirm your exact variant and driveline with the workshop before ordering — header fitment is unforgiving of small differences.
Oak Flats Muffler Men supplies and fits extractor packages like this in-house across the Illawarra. Header swaps on a tightly packaged V8 mean checking clearances, gaskets and the full 2.5in run as one job. At an RRP of $6,358.08 this is a special-order set — send us your build and we'll confirm fitment and book the bay.
