Built around a 3in bore, the MPI Automotive SSMKHN0178 is a chambered cat-back muffler section listed to fit the VE E2 in both Sedan and Wagon bodies. The larger pipe is the lever here — 3in suits a worked or higher-output V8 wanting more flow than a stock-diameter system gives.

Why the 3in bore?

The SSMKHN0178 runs 3in throughout the cat-back span, the wider of the common Commodore-platform sizes. A bigger bore drops back-pressure and lets a healthier engine breathe out, which is why it tends to be the pick for cars that have moved past standard. It keeps a chambered muffler rather than a straight-through can, so the note is fuller without turning harsh — a measured trade-off, not an all-out volume grab.

Sedan or Wagon — will it fit mine?

This part is listed to fit the VE E2 in Sedan and Wagon form across the Holden and HSV range. The two bodies route their rear sections differently, and this listing covers both shells. Confirm your exact variant and rear-end layout with the workshop before ordering so the hangers and tailpipe exit line up.

What's a chambered muffler doing in the system?

A chambered muffler quietens by bouncing and absorbing pressure pulses inside internal baffles, which is the more subdued path compared with a free-flowing straight-through design. On a 3in V8 cat-back it keeps cruise manners civil while still letting the engine sound like it makes power. There's no published decibel data, so we describe it by type rather than a figure.

What does fitting involve at Oak Flats?

Oak Flats Muffler Men supplies and fits this MPI section in-house across the Illawarra. We check the cat-back flange, hanger positions and tailpipe clearance against your VE E2 before booking the bay. At an RRP around the higher end of the range, it's typically a special order — send your build and we'll confirm stock and timing.

Common questions

Does the SSMKHN0178 suit a modified V8?
The 3in bore is the larger of the common sizes and is generally chosen for engines that have moved beyond stock. It's listed to fit the VE E2; confirm your build with the workshop.
Will it fit both the Sedan and the Wagon?
Yes — this listing covers the VE E2 in Sedan and Wagon bodies. We'll confirm your exact rear layout before ordering.
Is this a loud system?
It uses a chambered muffler, which is the more subdued design rather than a straight-through. We have no decibel data, so we describe it by type only.
