Built for the IRS sedan, the MPI Automotive MKHN0389 is a 2.5in extractor-and-tailpipe system listed to fit the Holden Commodore VP/VR/VS Sedan 5L V8 Auto with independent rear suspension. The IRS routing and 5L automatic driveline are what set this earlier-Commodore build apart.

What does the IRS routing mean for this sedan?

The MKHN0389 is listed for the Holden Commodore VP/VR/VS Sedan with the 5L V8, automatic, and independent rear suspension. The IRS qualifier shapes the under-floor path, since the independent-rear cradle differs from a live-axle car. It's an extractor-and-tailpipe build: tubular extractors at the heads feed a 2.5in run finishing in a tailpipe, sized for this earlier Commodore sedan driveline.

What does the extractor and 2.5in run change?

Tubular extractors replace the cast manifolds with runners off each port, easing the merge at the heads. On the MKHN0389 they feed a 2.5in system to a tailpipe — a complete engine-back package for the IRS 5L sedan rather than headers alone. We have no published flow or sound figures, so the value is the IRS-specific routing and the matched 2.5in build, not a measured claim.

Will it suit my VP, VR or VS 5L Auto IRS Sedan?

It is listed to fit the Holden Commodore VP/VR/VS Sedan 5L V8 Auto IRS. The automatic, 5L and independent-rear qualifiers all matter for this fitment. Confirm your exact series, transmission and rear-suspension type with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits early Commodore sedan extractor systems in-house across the Illawarra. We confirm extractor access at the heads, then route the 2.5in run to the tailpipe around the IRS cradle. At an RRP of $2,663.27 it's a build-to-order item; send your VP-VS IRS details for fitment confirmation.
