Holden Commodore VZ 6.0 V8 2.5in Dual Catback WOM/Muffler.
Category: Mufflers and resonators


The MPI Automotive MKHN0264 is a 2.5in dual cat-back for the Holden Commodore VZ 6.0 V8 built without a rear muffler. The muffler-delete on a twin 2.5in path is what defines it — an opener note than the muffled VZ builds.
With no rear muffler in the run, there's no chambered box to absorb and reflect sound at the back, so the note opens up and the rear of the system flows more freely than a muffled build. On the MKHN0264's 2.5in dual layout, that makes for a harder, louder tone than the twin-muffler versions while keeping the same twin-path bore.
Two parallel 2.5in pipes from the cat rearward keep gas speed up across a twin path sized for the VZ 6.0 V8. It's a measured bore rather than the largest available, run as a true dual system. Pairing that with the muffler-delete gives a system that flows freely at the back while staying on the 2.5in path front-to-rear.
As a cat-back, the MKHN0264 sits behind the catalytic converter and doesn't touch the factory cat. With no rear muffler the noise picture changes, so compliance depends on noise limits and your state's rules — confirm the exact build and any NSW requirements with the workshop before fitting.
It's listed to fit the Holden Commodore VZ 6.0 V8; the supplier names the V8 but not exact years, so confirm your variant with us. Oak Flats Muffler Men fits the MKHN0264 in-house, lining up both 2.5in paths and the rear section for clearance as it goes up.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
