Holden Commodore VP VR VS Sedan 5L V8 Auto IRS 2.5in With Extractors Tailpipe.
Category: Extractors and headers


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.
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.
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.
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.
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.
