MPI Automotive Isuzu D-Max + Holden Colorado RG 3in Centre Hotdog.
Category: Mufflers and resonators


The MPI Automotive SSMBM597PHD is a 3in centre hotdog listed to fit the Isuzu D-Max and Holden Colorado RG. The hotdog format — a single compact straight-through resonator mid-system — is what defines this part against a full muffler.
A hotdog is a short straight-through resonator: a perforated core in packing that flows freely while taking harshness off the note. It suits an owner who wants the rasp settled on a 3in ute exhaust without the volume drop a chambered muffler brings, which is why it's a popular centre choice on the D-Max and Colorado. It keeps the system flowing while knocking the worst of the drone out of the cabin at cruise.
At 3in it's sized for an upgraded D-Max / Colorado RG exhaust, mounted in the centre of the system so the resonating happens mid-run rather than at the tail. A single centre hotdog keeps the package compact under the floor of the ute, which matters where the chassis rails and crossmembers limit how big a box can sit. It pairs with whatever rear section the ute runs.
It's listed to fit the Isuzu D-Max and the Holden Colorado RG; confirm your exact model year and build with the workshop before ordering so the centre-section pipework lines up. The two utes share their platform and exhaust layout, which is why a single part covers both, but the build still has to be checked rather than assumed from the badge.
Oak Flats Muffler Men fits centre hotdogs like this in-house across the Illawarra. We check the under-floor routing, the hanger spacing and the pipe sizing on the hoist, then book the bay once your build is confirmed. The RRP is listed, and we'll confirm the part suits your existing system before ordering it in.
