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


This is the IRS listing: the MPI Automotive SSMKHN0064TC is a 2.5in extractor-and-muffler system for the VP-VR-VS Commodore 5L V8 sedan fitted with independent rear suspension. The IRS rear end changes the pipe routing, which is why it's catalogued separately.
Independent rear suspension changes the geometry under the back of a VP-VR-VS sedan — the diff, the rear cradle and the available clearance all sit differently to a live-axle car. The SSMKHN0064TC is the IRS-specific listing, so its 2.5in pipework and muffler are routed to clear that rear end. Fitting the wrong rear-end version is the classic mismatch on these cars, which is why we confirm IRS versus live axle before ordering.
It's a header-back system: tuned-length extractors at the cylinder heads, a 2.5in run and a muffler. The factory cast manifolds and the original VP-VR-VS exhaust come out together and the SSMKHN0064TC goes in as one matched set, with the primaries sized to the 2.5in pipe so the V8 system flows as a unit on the IRS sedan.
Extractors replace the restrictive cast manifolds the 5L V8 wore from the factory, giving each cylinder its own primary tube before the merge to cut back-pressure and improve scavenging. The honest catch: they sit in the engine-bay heat zone, take labour to fit, and change the note. The single muffler here lifts the sound over stock without the silencing of a multi-muffler layout.
Oak Flats Muffler Men supplies and fits MPI extractor systems like this across the Illawarra. The work means removing the factory manifolds, hanging the extractors, then routing the 2.5in pipe and muffler with clearance checks around the IRS rear cradle. It's listed to fit the VP-VR-VS 5L V8 IRS sedan; at an RRP of $4,678.12 it's a special-order set, so we confirm your rear-end type and lead time before booking the bay.
