The MPI Automotive SSMKHN0061 is a full 3in system for the manual IRS V8 sedan that runs a centre muffler only — no rear can — so it leans toward a freer, louder note. It's built for the VP, VR and VS Commodore 5.0L V8.

What does centre-muffler-only mean for the note?

With a centre muffler but no rear silencer, the SSMKHN0061 carries less absorption than a dual-muffler system, so the V8's voice comes through harder and more open. It's the louder of the full 3in builds for this car — the choice when you want the V8 to be heard rather than hushed, while the centre muffler still takes the edge off.

Why a full 3in with the cat retained?

This is a complete 3in run rather than a cat-back, with the catalytic converter kept in place. The 3in bore is matched to the 5.0L V8 — sized to the engine rather than over-bored. Keeping a single centre muffler is what gives it the more open character.

Is it road legal?

The system retains the catalytic converter, so the factory emissions hardware on the V8 stays in place — the usual compliance sticking point. Confirm the exact build and any state requirements with the workshop before fitting.

Will it suit my IRS manual V8 sedan?

It's listed to fit the Holden Commodore VP, VR and VS 5.0L V8 IRS sedan in manual form. Confirm your rear setup and transmission with us, then we'll fit it in our Illawarra bay.

Common questions

Is the SSMKHN0061 louder than a dual-muffler system?
Yes — it runs a centre muffler only, with no rear can, so it's the freer and louder of the full 3in builds. We can't quote a sound level.
Does it keep the catalytic converter?
Yes — it's a with-cat full 3in system, so the factory cat stays in place.
