Holden VX VY V8 Monaro 2.5in Dual With Extractors Hotdog/Muffler (SKU: MKHN0143) Engineered. Quality guaranteed.
Category: Extractors and headers


The MPI Automotive MKHN0143 is a 2.5in dual extractor-back exhaust listed to fit the Holden VX–VY V8 Monaro. It runs tuned extractors into twin 2.5in pipes with a hotdog resonator and a muffler, covering the full path from the heads back on the Monaro coupe.
This is a dual-pipe extractor-back package: tubular extractors at the heads feed two 2.5in lines rearward, with a hotdog resonator and a muffler handling the silencing. On the VX–VY Monaro V8 that's the complete exhaust path from the engine back. The twin 2.5in layout splits flow across two pipes, with two silencing stages keeping the note resolved on the coupe.
Extractors swap the cast manifolds for 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 takes the harsh edge off the note, while the main muffler does the heavier silencing. Running two stages on a dual system keeps a Monaro's V8 civil rather than droning, at the cost of more pipework than a single-pipe job.
It's listed to fit the Holden VX and VY V8 Monaro — the Commodore-based coupe of that era. Series and body matter, so a later or earlier car may take a different part. Treat the fit as listed to fit, not guaranteed, and confirm your exact build with the workshop before ordering.
