The MPI Automotive MKHN0255 is a 2.5in dual extractor-back exhaust listed to fit the Holden Commodore VY and VZ V8 one-tonner. It pairs tuned extractors with twin 2.5in pipes and is configured without a main rear muffler, so it's the louder, more direct end of the range.

What does this MKHN0255 system cover?

This is a dual-pipe extractor-back package for the VY–VZ one-tonner V8: tubular extractors at the heads feed two 2.5in lines rearward. It's listed in the 'without muffler' configuration, meaning it skips the main rear silencer that the muffler and hotdog versions of this car carry. On a working one-tonner body that covers the full exhaust path from the engine back, twin-piped at 2.5in.

What does running it without a muffler change?

Extractors swap the cast manifolds for tubular runners to ease back-pressure off the heads. Leaving out the main rear muffler removes the biggest silencing stage, so this configuration is louder and more direct than the hotdog or twin-muffler builds MPI lists for the same one-tonner. The trade-off is plain: less in-cabin quiet and a sharper note. If you want it tamer, the muffler-equipped versions exist — this one is for buyers who want the rawer setup.

Will it suit my VY–VZ one-tonner?

It's listed to fit the Holden Commodore VY and VZ V8 in one-tonner form. The one-tonner body and its tray-back rear shape the pipework, so that body is part of the listing. Treat the fit as listed to fit, not guaranteed, and confirm your exact series and build 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 one-tonner fitment, check extractor and chassis clearances, and talk through the without-muffler volume before booking the bay.
