VY VZ HSV V8 SDN 2.5in Dual With Extractors Muffler/Tailpipe (SKU: MKHN0131) Engineered. Quality guaranteed.
Category: Extractors and headers


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.
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.
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.
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.
