Holden Commodore VT - VZ V8 Sedan 3in Dual With 1 7/8 in Extractors Hotdog/Muffler.
Category: Extractors and headers


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.
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.
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.
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.
