This is the centre muffler on its own — the M4948 Mega Flow mid-system box: the HOLDEN-STATESMAN-VS-V6-8-2-1-2-CENTRE-MUFFLER-MEGA-FLOW-M4948 from Exhaust Systems Australia is a 2in centre muffler listed for the VS Statesman in both V6 and V8.
What does the M4948 centre muffler do?
Sitting mid-system rather than at the tail, this Mega Flow centre muffler does the middle stage of silencing on the VS Statesman. It's the box alone — not a full system — so it's the part you fit when the centre muffler has rusted or blown and the rest of the exhaust is sound. Built on a 2in body, it covers both the V6 and V8 Statesman and works alongside the rear of the system rather than setting the final tailpipe note on its own.
How does the Mega Flow centre muffler shape the note?
A muffler quietens by absorbing and reflecting sound inside its body, and the Mega Flow centre box takes the edge off mid-run before the gas reaches the rear. As a centre muffler it shapes the sound in the middle of the system rather than at the tail. There's no published sound figure, so the honest test is to hear a comparable VS Statesman fit before deciding.
Will it suit my VS Statesman?
It's listed to fit the Holden Statesman VS in both V6 and V8 on a 2in body. Because the same centre box covers both engines, confirm your exact engine and that the centre muffler is the part that's failed with the workshop before ordering.
