VY VZ V8 HSV Sedan 3in Dual With 1 7/8 in Extractors Hotdog/Muffler (MKHN0136) Fits HOLDEN. Fast.
Category: Extractors and headers


The MPI Automotive MKHN0136 is a 3in dual extractor-back exhaust listed to fit the VY and VZ V8 HSV sedan. It runs 1-7/8in tubular extractors into a 3in dual system with a hotdog resonator and a muffler, the larger-bore street build for these HSV sedans.
This package starts at the cylinder heads with 1-7/8in tubular extractors and runs a 3in dual system rearward through a hotdog resonator and a muffler. On the VY and VZ HSV sedan that's the complete exhaust path from the engine back. The 3in dual bore is the larger pipework on offer here, and the hotdog-plus-muffler combination sits between a stripped line and a fully silenced build for noise.
Extractors replace the cast factory manifolds with tubular runners that merge downstream, easing back-pressure off the heads and changing how the V8 breathes. The 1-7/8in primary size sets the runner diameter, and the 3in dual layout carries two pipes rearward. A hotdog resonator paired with a muffler tames the note more than a resonator alone but stays louder than stock. The trade-off is plain: more pipe and tubular runners over the cast manifolds, with the resonator-and-muffler pairing keeping it street-civil.
It's listed to fit the VY and VZ V8 HSV in sedan body — both series across the one part, with the V8 driveline assumed. A wagon, ute or six-cylinder Commodore will need a different listing. Treat the fit as listed to fit, not guaranteed, and confirm your exact HSV series and build with the workshop before ordering.
Oak Flats Muffler Men fits extractor systems like this in-house across the Illawarra. We confirm the VY or VZ HSV sedan fitment, check the 1-7/8in extractor clearances and align the 3in dual routing, the hotdog and the muffler before booking the bay. As an MPI Automotive system it can be special-ordered in if it's not on the shelf.
