The MPI Automotive MKHN0254 is a 2.5in dual extractor-back exhaust listed to fit the Holden Commodore VY and VZ V8 one-tonner. It runs tuned extractors into twin 2.5in pipes with a hotdog resonator and a muffler, the more silenced version for this body.

What does this MKHN0254 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 back, with a hotdog resonator and a muffler doing the silencing. On the one-tonner body that's the whole exhaust path from the engine rearward. Compared with the no-muffler version MPI lists for the same car, this is the tamer build.

What's a hotdog-and-muffler dual setup and what does it change?

Extractors replace the cast manifolds with tubular runners to ease back-pressure off the heads. The hotdog is a compact straight-through resonator that trims the harsh edge of the note, and the main muffler carries the bulk of the silencing. Running both on a dual system keeps a working one-tonner's V8 note resolved rather than droning on the road — the trade-off being more pipework and a quieter result than the without-muffler configuration.

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 rear shape the pipework, so that body is part of the listing. Treat the fit as listed to fit, not guaranteed, and confirm your 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 align the twin-pipe routing before booking the install.
