Routed for the IRS sedan rear end, the MPI Automotive MKHN0391 is a 3in system for the 5.0L V8 Holden Commodore VP-VR-VS sedan (auto), keeping the factory cat and running a single centre muffler. The IRS-specific sedan routing sets the packaging, and the centre-muffler-only layout gives a more present V8 note.
Why does the IRS sedan routing matter?
This system is cut for the VP-VR-VS sedan fitted with independent rear suspension, so its rear-section pipe lengths and hanger points clear the IRS cradle rather than a live-axle floorpan. That's the first thing to get right — a system bent for one rear end won't sit correctly on the other. The MKHN0391 is the build for an IRS sedan owner who wants a full 3in run packaged around that rear.
What does centre-muffler-only do here?
It uses a single centre muffler rather than a pair, so there's one absorptive stage in the run. On a 5.0L V8 sedan that leans the note toward more presence — fewer damping elements between the engine and the tailpipe than a dual-muffler arrangement. The cat stays in place, so the emissions hardware is as the Commodore left the factory; confirm any state requirements with the workshop before fitting. The MKHN0391 carries a published RRP of $2,568.16.
Will it suit my Commodore sedan?
It's listed to fit the 5.0L V8 auto Holden Commodore IRS sedan across the VP, VR and VS series. Confirm your exact series, rear end and driveline with the workshop before ordering.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits MPI Commodore systems in-house across the Illawarra. We confirm the IRS routing, check clearances along the 3in run, set the centre muffler, and match the part to your sedan before it goes on the hoist.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Is this for an IRS sedan?
- Yes — it's routed for the VP-VR-VS sedan with independent rear suspension. Confirm your rear end with the workshop before ordering, as a system bent for one rear won't suit the other.
- How does centre-muffler-only sound versus dual?
- One centre muffler means a single absorptive stage, so it's a more present note than a dual-muffler version. We don't publish decibel figures.
- Does the MKHN0391 keep the catalytic converter?
- Yes — this is the with-cat 3in system, so the factory catalytic converter stays in place. Confirm any state requirements with the workshop before fitting.
