The MPI Automotive SSMBM591MF is a 3in centre muffler listed to fit the Holden Colorado 7 / Trailblazer and the Isuzu MU-X. As a chambered muffler it leads on quietening — it's the more subdued of the silencing options for these wagons.

What does a chambered centre muffler do?

A chambered muffler uses internal baffles to reflect and absorb sound, so it cuts volume more than a free-flowing resonator does. Mounted in the centre of the Colorado 7 / Trailblazer or MU-X system, it takes the bulk of the silencing duty mid-run and keeps the wagon quiet for daily and touring use, which is the choice for owners who want the cabin settled rather than the exhaust opened up.

Why 3in for these wagons?

At 3in it's sized for an upgraded exhaust on these turbo-diesel wagons rather than the factory pipe. It's a single centre muffler that covers the Colorado 7 / Trailblazer and the MU-X, all of which share the platform and the centre-section layout, so one part suits the range. It pairs with whatever rear section the wagon is running.

Will it suit my Trailblazer or MU-X?

It's listed to fit the Holden Colorado 7 / Trailblazer and the Isuzu MU-X; confirm your exact model year and build with the workshop before ordering so the centre pipework lines up. If the wagon already runs a modified rear or front section, the centre box has to suit that, which is why we check the full run rather than the badge.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits centre mufflers like this in-house across the Illawarra. We check the mid-system hangers, the under-floor clearance 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 muffler suits your existing system before ordering it in.

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