The MPI Automotive MKHN0131 is a 2.5in dual extractor-back exhaust listed to fit the VY–VZ HSV V8 sedan. It runs tuned extractors into twin 2.5in pipes finished through a muffler to a tailpipe, the single-stage 2.5in build for the HSV sedan.

What does this MKHN0131 system cover?

This is a dual-pipe extractor-back package: tubular extractors at the heads feed two 2.5in lines rearward, finishing through a muffler to a tailpipe. On the VY–VZ HSV V8 sedan that's the complete exhaust path from the engine back. The twin 2.5in layout with a single muffler-and-tailpipe finish is the simpler-silencing option compared with the hotdog or twin-muffler versions MPI lists for this car.

What are extractors and what do they change?

Extractors replace the cast factory manifolds with separate tubular runners, one per cylinder, that merge downstream. The aim is to reduce back-pressure and let each cylinder's pulse clear with less interference, which generally helps a V8 breathe and changes the exhaust note. The muffler then silences the rear before the tailpipe. Running a single silencing stage on a 2.5in dual makes this a touch sharper than the twin-muffler build, while staying tamer than a no-muffler setup.

Will it suit my VY–VZ HSV sedan?

It's listed to fit the VY–VZ HSV V8 in sedan body — the HSV-built version of that Commodore era. Series and body both matter, so a wagon, ute or non-HSV car may take a different part. Treat the fit as listed to fit, not guaranteed, and confirm your exact HSV variant with the workshop before ordering.

What does fitting involve at our Illawarra workshop?
