Built around a 3in dual rear layout, the MPI Automotive MBM449HSV is a pair of rear mufflers listed to fit the Holden VY-VZ HSV sedan. The 3in bore marks it as the bigger-pipe rear box rather than a stock-sized replacement, sized for the V8 sedans it sits behind.
What does the 3in bore suit?
Bore is the pipe size a muffler is built to flow, and at 3in the MBM449HSV is on the larger side — the size you step to on a modified or higher-output V8 rather than a small or stock engine. Running as a dual rear set, it carries gas out the back of the car through two paths, which suits the twin-exit HSV sedans this is listed for. It's a chambered rear muffler, so it quietens by absorption and reflection rather than running straight through.
What's a rear muffler and where does it sit?
The rear muffler is the last silencing box before the tailpipe — it sets a lot of the note you hear standing behind the car. As a dual 3in unit this replaces both rear boxes, so it's the back-of-system change on the VY-VZ HSV sedan rather than a full exhaust. The rest of the system ahead of it stays as it is.
Will it suit my VY-VZ HSV sedan?
It's listed to fit the Holden VY-VZ HSV sedan as a 3in dual rear muffler pair. Fitment data can be imperfect, so confirm the exact build and exit arrangement with the workshop before ordering.

Common questions

- It's a dual rear muffler set — two 3in rear boxes — listed to fit the Holden VY-VZ HSV sedan. Confirm your exit layout with the workshop.
- Why a 3in muffler rather than a smaller one?
- 3in is the larger bore, generally chosen for bigger or modified V8s. It flows more than a stock-sized box. Confirm it suits your build with us before ordering.
