Holden VX VY V8 Monaro 2.5in Dual Catback Hotdog/Muffler (SKU: SSMKHN0146) Engineered. Quality guaranteed.
Category: Mufflers and resonators


Finished with a hotdog, the MPI Automotive SSMKHN0146 is a 2.5in dual cat-back listed for the Holden VX-VY V8 Monaro. It pairs dual 2.5in routing with a compact hotdog resonator - the lighter-silenced twin-pipe build for the early Monaro V8.
This SSMKHN0146 runs two 2.5in pipes - a dual cat-back for the VX-VY Monaro V8. The twin-pipe layout splits the flow from the cat rearward, matched to the early Monaro's outlet arrangement rather than a single-bore run. The 2.5in bore is the moderate diameter that suits a standard or lightly-built V8, keeping gas speed up through the two paths rather than chasing the largest pipe size.
Instead of full chambered mufflers, this finishes through a hotdog - a compact straight-through resonator. It trims harshness and tunes the note while keeping flow free, the lighter silencing choice that sets it apart from a twin-muffler Monaro cat-back. A hotdog stays slim where a full muffler would take up more underbody space, which helps the packaging on the coupe.
A cat-back replaces the exhaust from the catalytic converter back, leaving the factory cat upstream. On the VX-VY Monaro that's the dual 2.5in run from the cat rearward through the hotdog - emissions hardware untouched, so it's the rear half of the system rather than a full engine-back change.
It's listed for the Holden VX-VY V8 Monaro. Oak Flats Muffler Men supplies and fits 2.5in dual cat-backs in-house across the Illawarra - send your exact build so we can confirm fitment before ordering.
