The MPI Automotive MKHN0383 is the dual-muffler full system for the Holden Commodore VN-VS sedan 5.0L V8 (auto), at 2.5in and with the catalytic converter retained. Twin mufflers set it apart — more silencing surface than a single-can layout.

What do dual mufflers change here?

The defining feature of MKHN0383 is its dual-muffler layout: two mufflers rather than a single centre can give more silencing volume across the system, so the V8 note is reined in more than a centre-muffler-only build while still flowing at 2.5in. The catalytic converter is retained, keeping the emissions hardware in line. It's the quieter-leaning full system in this VN-VS V8 sedan range.

Is it road legal?

Because MKHN0383 keeps the catalytic converter, the Commodore's factory emissions equipment stays in place. Sound output and local rules still need checking, so confirm the exact build and your state's requirements with the workshop before fitting.

Will it suit my VN-VS Commodore?

It's listed to fit the Holden Commodore VN, VP, VR and VS sedan with the 5.0L V8 and automatic. These span several series, so confirm your exact variant before ordering. Feed data can be imperfect, so we treat the fitment as listed-to-fit rather than guaranteed and check it against the vehicle in front of us before committing to the install.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this dual-muffler 2.5in Commodore system in-house across the Illawarra. We check sedan routing, hang both mufflers and the pipework, and confirm the cat. RRP is $2,594.85, available to order. Stock is held by MPI Automotive and brought in to order, so we confirm availability when we book the job in.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

Common questions

How is MKHN0383 different from the centre-muffler version?
This system uses dual mufflers for more silencing surface, so it leans quieter than a centre-muffler-only layout. Both are 2.5in with the cat retained.
Is it road legal?
It keeps the catalytic converter, so the emissions hardware stays in place. Confirm sound output and your state's rules with the workshop.
