Listed across the VT to VZ sedan, the MPI Automotive MKHN0399 is a 3in dual extractor system for the Holden Commodore VT-VZ V8 Sedan, finishing through a muffler-and-muffler rear. It's the twin-muffler sedan build, with the primary tube size not called out in the listing.

What does this VT-VZ sedan system cover?

The MKHN0399 is listed across the VT through VZ V8 sedan — the long single-generation Commodore sedan platform. It runs a 3in dual system off tubular extractors at the heads into two mufflers, the most settled rear arrangement among these sedan builds. Unlike some siblings, the supplier listing for this part doesn't call out a specific primary tube size, so we describe it simply as a tubular extractor system without quoting a bore for the primaries.

What does a tubular extractor change?

Extractors replace the factory cast manifolds with runners off each port, easing the path gas takes to merge off the heads. On the MKHN0399 those extractors feed the full 3in dual run, making this a complete engine-back package rather than headers alone. Two mufflers handle silencing for a quiet-leaning note. We have no published flow or sound figures, so the value sits in the matched, sedan-sized 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 prior exhaust changes with the workshop before ordering, as feed data can be imperfect.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits Commodore sedan extractor systems in-house across the Illawarra. We confirm extractor access at the heads, then route the 3in dual run and both mufflers under the sedan floor. At an RRP of $4,553.30 it's a build-to-order package; send your VT-VZ details for fitment confirmation.
