The MPI Automotive SSMBM123PHD is a dual centre assembly with hotdog resonators for the Holden Commodore VP/VR/VS V8 IRS sedan. Running twin hotdogs in the centre section is what defines it — a straight-through tuning approach rather than chambered mufflers.

What does a dual centre with hotdogs do?

This is the middle section of a dual exhaust, fitted with hotdog resonators in each pipe. Hotdogs are compact straight-through resonators, so they trim resonance and drone in the centre of the system while keeping flow up — quite different from dropping in chambered mufflers. It's the mid-section tuning piece for the VP/VR/VS V8, aimed at owners who want to settle the note without a heavy silencer.

What does the 2in bore suit?

The centre assembly runs at 2in. Twin hotdogs in a dual 2in layout suit a V8 sedan owner who wants to settle the note through the middle of the system without a heavy chambered muffler, while keeping the pipework proportionate to the car rather than oversizing it for a road-driven sedan.

Will it fit my Commodore V8?

It's listed to fit the Holden Commodore VP, VR and VS V8 IRS sedan. The record doesn't publish model years, so confirm your exact car and rear-end setup with the workshop before ordering — IRS fitment matters here. RRP is $1,124.24.

Fitting at our Illawarra workshop

Oak Flats Muffler Men fits centre assemblies like this on-site. With an IRS sedan, we check clearance around the independent rear, how the dual pipes mate front and rear, and hanger alignment before sign-off so the assembly sits clean against your existing front and rear sections.

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

Common questions

What are the hotdogs in the SSMBM123PHD?
Compact straight-through resonators fitted in each pipe of the dual centre section. They cut drone while keeping the system free-flowing — not chambered mufflers.
Does it fit a live-axle Commodore?
It's listed for the VP/VR/VS V8 IRS sedan specifically, so confirm your rear-end setup with the workshop before ordering.
