The MPI Automotive MKHN0390 pairs the IRS sedan routing with dual mufflers: a 3in system for the 5.0L V8 Holden Commodore VP-VR-VS sedan (auto), keeping the factory cat. Two mufflers around the IRS-specific rear give the most subdued V8 character in this sedan family.

Why the IRS sedan routing plus dual mufflers?

This system is cut for the VP-VR-VS sedan with independent rear suspension, so its rear pipework clears the IRS cradle rather than a live-axle floorpan — get the rear end right first. On top of that it runs two mufflers, so there are two absorptive stages in the run. The combination makes the MKHN0390 the most refined of these sedan builds: full 3in pipework packaged for the IRS rear, with the V8 note kept the most in check at cruise.

What's a full 3in system, and is the cat kept?

This is a complete 3in run — the larger bore suits the 5.0L V8 — and it keeps the factory catalytic converter in place. Retaining the cat leaves the emissions hardware as the Commodore left the factory, which matters for road compliance. Confirm any state requirements with the workshop before fitting. The MKHN0390 carries a published RRP of $2,764.78.

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 both mufflers, 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, as a system bent for one rear won't suit the other.
Why choose dual mufflers?
Two mufflers give two absorptive stages in the run, so it's the most subdued of these sedan builds. We don't publish decibel figures.
Does the MKHN0390 keep the catalytic converter?
Yes — this is the with-cat full 3in system, so the factory catalytic converter stays in place. Confirm any state requirements with the workshop before fitting.
