The MPI Automotive SSMKHN0132 is a dual 2.5in cat-back with a chambered muffler on each bank, listed to fit the VY HSV V8 Sedan. Twin 2.5in mufflers are the angle — a balanced, settled dual build sized for a near-stock or lightly worked HSV V8.

What does dual 2.5in with twin mufflers suit?

The SSMKHN0132 splits into two 2.5in banks, each carrying a chambered muffler. The 2.5in bore is the keener of the common sizes, sized to keep gas speed up on a near-stock or lightly modified V8 rather than chase the largest pipe. Twin mufflers give sound control across both exits. We quote only the 2.5in diameter MPI lists for this part.

Why chambered mufflers?

Chambered mufflers reflect and absorb pressure pulses through internal baffles, the more subdued design versus a straight-through hotdog. On a dual HSV sedan that means a measured note at idle and cruise across both exits. There's no published decibel data, so we describe the system by its muffler type.

Will it fit my VY HSV?

The SSMKHN0132 is listed to fit the VY HSV V8 Sedan across the Holden and HSV range. The dual rear routing is model-specific, so confirm your exact build and rear-end layout with the workshop before ordering so both banks, hangers and exits line up.

Common questions

Is the SSMKHN0132 quieter than a hotdog build?
It uses chambered mufflers on both banks rather than straight-through hotdogs, so it's the more subdued option. We describe sound by type, not decibels.
Does 2.5in suit a stock HSV V8?
The 2.5in bore is the keener of the common sizes and suits a near-stock or lightly worked engine. It's listed to fit the VY HSV V8 Sedan.
Is it a dual system?
Yes — dual 2.5in cat-back with twin mufflers. Confirm your VY HSV build with the workshop.
