Isuzu D-Max Mazda BT50 2021 Onwards, 3in Centre Pipe without Muffler for selected vehicle applications.
Category: Mufflers and resonators


The MPI Automotive MBM617WOM is a 3in centre pipe without a muffler for the Isuzu D-Max and Mazda BT-50 from 2021 onwards — a straight mid-system pipe that deletes the centre silencer to free flow and lift the note through the middle of the run.
The defining feature is what's missing: there's no centre silencer, just a straight 3in pipe where one would sit. On the 2021-on D-Max and BT-50 that removes a sound-control point from the middle of the system, so the exhaust flows freer and the note comes up. Pair it with a rear muffler and you keep some manners; run it into a freer rear and it gets noticeably louder.
It fits an owner building a freer-flowing exhaust on the shared D-Max/BT-50 platform who wants to drop a restriction from the middle without going fully muffler-less front to back. Because it's a centre section, the final volume depends on what you keep at the rear — it's a building block, not the whole story.
The MBM617WOM is listed to fit the Isuzu D-Max and Mazda BT-50 from 2021 onwards, in 3in. The supplier doesn't publish an engine listing for this part, so confirm your exact model, year and the rest of your system with the workshop before ordering.
Oak Flats Muffler Men fits these in the Illawarra. We line the straight centre pipe into the mid-system position, check clearance to the floor and crossmembers, and weld or clamp it in. Since it changes the note, we'll talk through the result with you before finishing.
