VF HSV V8 Sedan Wagon 3in Catback Hotdog/Muffler (MKHN0334) Fits HOLDEN. Fast shipping, warranty included.
Category: Mufflers and resonators


For the VF HSV V8 in sedan and wagon form, the MPI Automotive MKHN0334 is a 3in cat-back running a hotdog and a rear muffler. The sedan/wagon body routing is the distinction — a different underbody path from the ute version.
The MKHN0334 is shaped for the VF HSV V8 sedan and wagon bodies, which run their exhaust along a boot-and-floor path rather than under a ute tray. That body-specific routing is why it carries its own part number. The 3in bore is sized for the V8 and carried from the cat rearward in a layout built around the sedan/wagon underbody.
The hotdog is a compact straight-through resonator that trims resonance with little restriction, while the rear muffler is a chambered box that absorbs and reflects sound to settle the note. Together they let the centre of the system flow freely while the rear keeps the tone composed — a tuned pairing on this V8 cat-back rather than a single quietening device.
Being a cat-back, the MKHN0334 sits behind the catalytic converter and doesn't touch the factory cat — that component isn't part of this section. Compliance still comes down to noise limits and your state's rules, so confirm the exact build and any NSW requirements with the workshop before fitting.
It's listed to fit the VF HSV V8 sedan and wagon; the supplier names the V8 and the body styles, so confirm your exact variant with us. Oak Flats Muffler Men fits the MKHN0334 in-house across the Illawarra, lining up the 3in routing, hotdog and rear muffler for clearance as it goes up.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
