Built around 1-3/4in primary extractors, the MPI Automotive MKHN0437 is a 3in system listed to fit the VF HSV V8 in sedan and wagon. The 1-3/4in primary size keeps gas speed up for street response, finished here with a hotdog and rear muffler.

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

The MKHN0437's primaries are 1-3/4in. On a street-driven V8 like the VF HSV's, 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. It's a sensible match to the 3in downstream pipe, so the system flows as a set off the cylinder heads through to the rear, across both the sedan and wagon bodies.

What does the package cover?

It's a header-back system: 1-3/4in primary extractors at the cylinder heads, a 3in run, a hotdog resonator and a rear muffler. The factory cast manifolds and the original VF exhaust both come out and the MKHN0437 goes in as one matched set. The hotdog tidies the mid-range rasp while the rear muffler carries the main silencing, so the HSV's note is shaped rather than left raw.

What's an extractor and what's the trade-off?

Extractors are tuned-length headers replacing the restrictive cast manifolds the V8 wore from the factory, giving each cylinder its own primary tube before the merge to cut back-pressure and aid scavenging. The honest catch: they sit in the engine-bay heat zone, take labour to fit, and change the note. The 1-3/4in primaries here are matched to the 3in pipe so the system works together rather than as a header bolted to leftover plumbing.

Will it suit my VF HSV, and what's the fitting?

It's listed to fit the VF HSV V8 sedan and wagon — the record names both Holden and HSV. 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.

Does it fit the sedan and the wagon?
It's listed for the VF HSV V8 in both sedan and wagon. Confirm your exact body and build with the workshop before ordering.
Is it the full system or just headers?
