The MPI Automotive SSMKHN0254 is the one-tonner package for the Holden Commodore VY-VZ V8, running a 2.5in dual exhaust with a hotdog and rear muffler behind tube extractors. The 1-tonne cab-chassis is the distinguishing point — its longer chassis and tray mounts route the exhaust differently to a styleside ute.

Why a one-tonner-specific listing?

The VY-VZ 1-Tonner is a cab-chassis with a longer rear frame and different tray and hanger points than a standard ute. The SSMKHN0254 is bent for that one-tonne body, so the rear of the system mounts where the cab-chassis expects rather than where a styleside would.

How is the 2.5in dual silenced?

Behind the extractors, a 2.5in dual run carries a hotdog resonator and a rear muffler. The hotdog reduces drone and the muffler handles the main quietening, keeping the V8 useful as a working note rather than an intrusive one.

What does the 2.5in dual suit?

A 2.5in dual bore keeps gas speed sensible across the everyday rev range of a working VY-VZ V8, favouring low-down and mid response over top-end flow. Tube extractors at the head open the path the cast manifolds restrict.

How is it fitted locally?

Oak Flats Muffler Men in the Illawarra supplies and fits this in-house. It's listed to fit the VY-VZ Commodore V8 1-Tonner; bring the vehicle so we can confirm the chassis and tray mounts before booking.

How is it supplied?

This is a build-specific MPI Automotive package ordered against your confirmed VY-VZ 1-Tonner, not a shelf muffler. The cab-chassis routing differs from a styleside ute, so we match the body to the listing before ordering to keep the rear mounts right.
