Spanning the VT through VZ sedan, the MPI Automotive MKHN0400 is a 3in dual extractor system listed to fit the Holden Commodore VT-VZ V8 Sedan. It runs 1¾in primaries into a hotdog-and-muffler rear, making it the sedan-bodied build across that broad series range.

What does this VT-VZ sedan system cover?

The MKHN0400 is listed across the VT, VX, VY and VZ V8 sedan, the long single-generation Commodore sedan platform. It's the sedan routing — a 3in dual run sized for the car, off 1¾in tubular extractors at the heads, finishing through a hotdog resonator and rear muffler. That makes it the present-but-tame option among the VT-VZ sedan extractor builds rather than a wagon or ute fitment.

Why 1¾in primaries here?

The 1¾in primary tube is the application choice for a street V8 sedan: it holds gas velocity through the runners for low- and mid-range response rather than chasing peak high-rpm flow. Tubular extractors replace the cast manifolds, easing the merge off each port, then feed the 3in dual system. It's bought as a matched engine-back package — headers, pipework, hotdog and muffler. No flow or sound figures are published, so the value sits in the sizing and the complete build.

Will it suit my VT, VX, VY or VZ Sedan?

It is listed to fit the Holden Commodore VT-VZ V8 Sedan across those series. Confirm your exact series and any earlier driveline or exhaust work with the workshop before ordering, as feed data can be imperfect.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits Commodore sedan extractor systems in-house across the Illawarra. We confirm extractor access at the heads, then route the 3in dual run and locate the hotdog and rear muffler under the sedan floor. At an RRP of $4,412.20 it's a build-to-order item; send your VT-VZ details for fitment confirmation.
