The MPI Automotive MKHN0128 is a 3in dual extractor-back exhaust listed to fit the Holden Commodore VT to VZ V8 sedan. It pairs 1-7/8in primary extractors with twin 3in pipes, a hotdog resonator and a muffler, covering the full path from the heads back on the sedan body.

What does this MKHN0128 system cover?

This is a dual extractor-back package: 1-7/8in tubular extractors at the heads feed two 3in lines rearward, with a hotdog resonator and a muffler doing the silencing. On the VT-to-VZ Commodore V8 sedan that's the complete exhaust path from the engine back. The twin 3in layout with 1-7/8in primaries is the larger build here, with two silencing stages keeping the note resolved across that span of sedan series.

What do 1-7/8in extractors, a hotdog and a muffler do?

The 1-7/8in extractors replace the cast manifolds with tubular runners that merge downstream, easing back-pressure off the heads and changing how the V8 breathes and sounds. The hotdog is a compact straight-through resonator that trims the harsh edge of the note, and the muffler does the main silencing. Two silencing stages on a 3in dual temper the volume the bigger bore would otherwise carry — the trade-off being more pipework and weight than a single-pipe or single-stage build.

Will it suit my VT–VZ sedan?

It's listed to fit the Holden Commodore VT to VZ V8 in sedan body — a broad span of the V8 sedan era. Body matters, so a wagon or ute uses different rear pipework. Treat the fit as listed to fit, not guaranteed, and confirm your exact series and build with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits 3in dual extractor systems like this in-house across the Illawarra. We confirm the VT–VZ sedan fitment, check the 1-7/8in extractor clearances and align the twin 3in routing and silencers before booking the install.
