Holden VY - VZ 5.7L V8 1 ton Ute, Crewman 2 1/2in Dual Centre Assembly W/out Muffler for selected vehicle applications.
Category: Mufflers and resonators


The MPI Automotive MBM378WOM is a 2in dual centre assembly supplied without a muffler, listed to fit the 5.7L V8 Holden VY-VZ 1-Tonner and Crewman ute. The without-muffler centre is the defining feature — it replaces the mid-system silencer with open dual pipe.
Instead of a chambered centre silencer, the MBM378WOM is a straight-through dual centre — it deletes the factory mid-system muffler and runs clear dual pipe in its place. That opens up the middle of the system for a louder, harder note than stock, while the rear silencing stays to keep it civil at the tail. It's the centre-delete path for owners who want more sound without changing the rear.
It's a dual assembly, carrying two paths through the centre to match the dual layout of these utes. At 2in per side the bore suits the 5.7L V8 in a road-driven 1-Tonner or Crewman, keeping gas speed up rather than going oversized. The same centre suits both the long-wheelbase and crew-cab bodies that share this underbody.
It's listed for the 5.7L V8 VY-VZ 1-Tonner and Crewman. Send your exact model and build and we'll confirm the centre length and hanger spacing before ordering, since these utes had running changes.
Oak Flats Muffler Men fits the MBM378WOM in-house, clamping or welding the dual centre in and aligning it clear of the chassis and driveline. Book the ute in and we'll confirm the fitment against your build.
