This is the E3-series listing: the MPI Automotive MKHN0427 is a 3in system with 1-3/4in primary extractors, listed to fit the HSV VE E3 in sedan and wagon. Matched to the E3 update of the VE HSV range, it finishes through a hotdog and rear muffler.

Why an E3-specific listing?

The MKHN0427 is catalogued for the HSV VE E3 — the later series of the VE-era HSV range — in sedan and wagon form. Series and body both shape how the extractors and 3in pipework route under the car, so matching the E3 listing to an E3 car is what keeps the fitment honest. The record names both Holden and HSV for this part, and the exact build is what we confirm before anything is ordered.

What does 1-3/4in primary tubing suit?

The MKHN0427 runs 1-3/4in primaries. On a street-driven engine that primary size keeps exhaust-gas speed up for low-down and mid-range response rather than chasing the larger bore a high-rpm build wants. They're sized to the 3in downstream pipe so the system flows as a set off the heads through to the rear, across both the sedan and wagon.

What's an extractor, and what's the back end?

Extractors are tuned-length headers replacing the restrictive cast manifolds the engine wore from the factory, giving each cylinder its own primary tube before the merge to cut back-pressure and aid scavenging. The honest trade-offs: they sit in the engine-bay heat zone, take labour to fit, and change the note. The back end here runs a hotdog resonator to tidy the mid-range and a rear muffler for the main silencing.

Will it suit my VE E3, and what's the fitting?

It's listed to fit the HSV VE E3 sedan and wagon; send your build and Oak Flats Muffler Men will confirm it before ordering. Fitting at our Illawarra workshop means removing the factory manifolds, hanging the 1-3/4in extractors, then routing the 3in pipe through the hotdog and rear muffler with clearance checks for your body. At an RRP of $4,676.00 it's a special-order set, so we confirm fitment and lead time first.

Common questions

Is this specific to the E3 series?
Yes — it's listed for the HSV VE E3 sedan and wagon. Confirm your exact series and body with the workshop before ordering, as the routing is tied to them.
Why 1-3/4in primaries?
On a street engine they keep gas speed up for low-down and mid-range response, matched to the 3in downstream pipe. We have no dyno data to quote.
Is it a full system or just headers?
It's a header-back system: 1-3/4in extractors plus a 3in run with a hotdog and rear muffler, supplied as one matched MKHN0427 kit.
