The MPI Automotive MKHN0129 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 with two mufflers, the quietest 2.5in build for the HSV sedan.
What does this MKHN0129 system cover?
This is a dual-pipe extractor-back package: tubular extractors at the heads feed two 2.5in lines rearward, with two mufflers handling the silencing. On the VY–VZ HSV V8 sedan that's the complete exhaust path from the engine back. Twin 2.5in pipes with twin mufflers make this the most thoroughly silenced of MPI's 2.5in builds for this car — quieter than the hotdog or muffler-to-tailpipe versions.
What does a dual twin-muffler setup change?
Extractors replace the cast manifolds with tubular runners that merge downstream, easing back-pressure off the heads and changing how the V8 breathes. Running a muffler on each of the two 2.5in lines gives more silencing than a single can, so the result is a calmer note. The trade-off is plain: this is the quiet, street-civil end of the range for the HSV sedan, with more muffling than the hotdog or single-muffler builds.
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?
Oak Flats Muffler Men fits dual extractor systems like this in-house across the Illawarra. We confirm the VY–VZ HSV sedan fitment, check extractor and steering clearances and align the twin 2.5in routing and both mufflers before booking the bay.
