Category: Extractors and headers


The MPI Automotive MKHN0412 is a 3in extractor-and-exhaust package built around 1-3/4in primary extractors, listed to fit the Holden Commodore VU, VY and VZ V8 ute. It runs left-and-right pipes with a hotdog-plus-muffler layout, so it's a header-back overhaul rather than a tailpipe swap.
This is a header-back package: it starts at the cylinder heads with 1-3/4in primary extractors and carries through to a 3in exhaust split into left and right pipes, running a hotdog resonator ahead of the main muffler. On a VU–VZ V8 ute, that means the factory cast manifolds and the original pipework both come out, replaced as one matched MKHN0412 kit. The L and R layout routes each bank down its own side of the floor.
Extractors (tuned-length headers) replace the restrictive cast-iron manifolds the V8 left the factory with. By giving each cylinder its own primary tube before they merge, they reduce back-pressure and help the engine scavenge spent gas more cleanly. The trade-off is honest: headers sit in the engine bay heat zone, take longer to fit than a bolt-on muffler, and change the exhaust note. The 1-3/4in primary size here is matched to the 3in downstream pipework so the system flows as a set.
It's listed to fit the Holden Commodore VU, VY and VZ V8 ute. Because it's an extractor-based system tied to a specific body and driveline, the exact build matters: send your ute's series and details and the workshop will confirm the fitment before anything is ordered.
Oak Flats Muffler Men supplies and fits MPI extractor packages like the MKHN0412 in-house across the Illawarra. Header work means removing the factory manifolds, fitting the primaries, then hanging the 3in left-and-right hotdog-and-muffler run and checking clearances along the floor and over the rear axle. At an RRP of $4,722.37 it's a special-order set, so we confirm the fitment and lead time with you before booking the bay.
