Built for a 2in bore, the MPI Automotive MBM165MF is a centre muffler listed to fit the V6 Holden Commodore VS sedan with IRS. Sitting mid-system, it does its silencing before the gas reaches the rear box, taming resonance through the cabin.

What does a centre muffler do?

A centre muffler is the mid-system silencing element, mounted under the floor between the front pipe and the rear box. Its job is to knock down the booming, mid-range resonance that travels into the cabin, doing part of the silencing so the rear muffler doesn't have to do it all. Replacing a rotted centre box is a common fix when a Commodore starts droning or rasping mid-length.

What does the 2in bore suit on a V6?

The muffler is sized for a 2in pipe, which matches the standard-to-mild output of the V6 Commodore. That's a sensible bore for the six — enough flow to breathe without dropping gas speed, and it keeps the note restrained rather than loud. It's the centre silencer for a VS V6 staying close to its factory exhaust sizing.

Will it suit my VS V6 sedan, and how do we fit it?

It's listed to fit the V6 Commodore VS sedan with independent rear suspension.
