Pairing the larger 1⅞in primaries with a twin-muffler exit, the MPI Automotive SSMKHN0331 is listed to fit the VF HSV V8 sedan and wagon. The 1⅞in primary tubing suits the higher-output, higher-rpm end of the HSV range, run on a 3in system that finishes muffler-to-muffler.

What does the 1⅞in primary size suit?

At 1⅞in, these extractors run a larger primary than the 1¾in street builds. A larger primary cross-section suits higher-rpm, higher-output engines — the matching sizing for a worked HSV V8 — rather than the low-down gas-speed bias of a narrower tube. It's general engine theory, with no flow or power figures published or quoted.

Why twin mufflers on the HSV sedan/wagon?

The SSMKHN0331 finishes muffler-to-muffler rather than with a hotdog resonator and a single muffler. Two muffler stages take the note down in two passes, so even on the larger 1⅞in extractors it's the more reserved exit. We publish no sound figure and won't quote one; the twin-muffler layout keeps the cabin settled.

Will it suit my VF HSV sedan or wagon?

It's listed to fit the VF HSV V8 in sedan and wagon. HSV variants differ across the range, so confirm your exact car with us against the listing before ordering. The body style sets the rear routing — this is the sedan/wagon build, not the ute.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits VF HSV systems in the Illawarra. We check the 1⅞in extractor flanges to your heads, route the 3in run, hang both mufflers with proper clearance, and seal the joints for heat cycling. RRP is listed at 5938.34 AUD; fitting is quoted once we've seen the car.

Common questions

What's the benefit of the 1⅞in primaries on the SSMKHN0331?
The larger 1⅞in primary suits higher-rpm, higher-output HSV V8 builds. It's an application choice rather than a power claim.
Is this the quieter HSV exit?
It runs two mufflers in series rather than a hotdog and one muffler, so it's the more reserved VF HSV sedan/wagon build. We don't publish a sound level.
