Category: Extractors and headers


The MPI Automotive HOLK128S3-178C is a full dual 3in system for the Holden Commodore VE-VF V8 sedan and wagon, built around coated 1-7/8in headers and finished with 3.5in tips. The larger 1-7/8in primary is the higher-output option in this range.
Primary size is an application choice, and the coated 1-7/8in headers here are the larger of the bores offered for this package. A bigger primary suits a higher-output, higher-rpm V8 build that is moving more air, where the extra cross-section pays off at the top end. The 178C marks the coated 1-7/8in primaries; a header coating manages surface heat and resists corrosion on the steel. The supplier has not published a coating temperature, material grade or sound rating, so we will not quote one.
Behind the headers this steps to a dual 3in system — two 3in pipes running the length of the car — finished with 3.5in tips at the rear. The 3in figure is the working pipe diameter; the 3.5in tip is the rear finisher you see. At the front, the headers replace the cast factory manifolds with tubular runners so the V8 breathes out more freely than the cast log allows. It is a deeper job than a tailpipe change, with clearance and gasket work to match.
It is listed to fit the Holden Commodore VE-VF V8 in sedan form, with the wagon covered by the same listing. The model years are not published in our record and V8 Commodore builds vary across that run, so confirm your exact variant and driveline with the workshop before ordering — header fitment leaves little room for guesswork.
Oak Flats Muffler Men supplies and fits header packages like this in-house across the Illawarra. A V8 header swap with a dual 3in system means checking clearances, gaskets and the full run through to the 3.5in tips. At $6,639.02 RRP it is a special-order set — send us your build and we will confirm fitment and book the bay.
