A straight-through resonator rather than a muffler, the MPI Automotive MBM591PHD is a 3in centre hotdog listed to fit the Holden Colorado 7, Trailblazer and the Isuzu MU-X. As a hotdog it tunes the note out of the middle of the run without choking the flow.
What is a centre hotdog resonator?
A hotdog is a compact straight-through resonator — a perforated core wrapped in packing, no baffles. Unlike a chambered muffler it doesn't reflect the gas back on itself, so it tidies the drone while staying open. On these wagon-bodied diesels it's the centre section for an owner who wants the note cleaned up rather than heavily silenced.
Why a 3in hotdog on the Colorado 7 and MU-X?
The 3in bore suits a free-flowing diesel run, and because the hotdog flows straight through it keeps that 3in open while taking the edge off the resonant frequencies. It's the leaner centre choice against a chambered muffler — more flow, a touch more presence, less of the boomy mid-range drone these big diesel wagons can carry.
Will it suit my Colorado 7, Trailblazer or MU-X?
It's listed to fit the Holden Colorado 7 and Trailblazer and the Isuzu MU-X. The supplier doesn't publish the engine or model years for this listing, so send your exact build and we'll confirm the centre-section fitment before ordering.
What does fitting involve in the Illawarra?
Oak Flats Muffler Men fits centre resonators like this in-house across the Illawarra. We confirm the 3in hotdog picks up cleanly mid-run, check clearances and hang it true. The MBM591PHD is a special-order item with a published RRP of $421.77.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Is a hotdog the same as a muffler?
- No — a hotdog is a straight-through resonator, so it tunes and tidies the note while staying more open than a chambered centre muffler. Confirm your Colorado 7 or MU-X build with the workshop.
- Will it make the diesel louder?
- It flows more freely than a chambered muffler, so it can sound a touch more present, but its job is cutting drone rather than adding volume. We can explain how it sits on your wagon.
