The MPI Automotive MKHN0303 pairs a compact hotdog resonator with a rear muffler in a 2.5in dual cat-back for the Holden WK/WL Statesman V8 — the hotdog-and-muffler mix is what sets this build apart and gives it a freer-breathing character than an all-muffler layout.
What does the hotdog bring to this build?
A hotdog is a short straight-through resonator: gas passes down a perforated core instead of being routed through chambers, so it trims drone and tunes the note while breathing more openly than a full muffler. Combined with a rear muffler on the MKHN0303, you get a 2.5in dual that lets the Statesman V8 talk a little more than a closed, all-muffler set without going fully open. It suits an owner chasing a touch more presence from the dual layout.
How is the 2.5in dual matched to the Statesman?
Two 2.5in pipes run rearward from the cat down both sides of the floor, a bore chosen to keep gas speed up across the twin path on a long-wheelbase WK/WL cruiser. The dual routing mirrors the V8's twin-outlet layout. The supplier lists the V8 fitment but not exact years, so we confirm the production variant with you before ordering.
Hotdog resonator versus a chambered muffler?
A muffler quietens by sending exhaust through baffled chambers; a hotdog resonator is a straight-through tube that targets specific frequencies to cut drone with less restriction. This SKU uses both — hotdog forward, muffler rear — so it sits between a fully chambered system and a straight-through one in how openly it breathes.
Road legality and fitting at Oak Flats
As a cat-back, the MKHN0303 sits behind the catalytic converter, leaving the factory emissions hardware in place; compliance then comes down to noise limits and your state's rules. Oak Flats Muffler Men supplies and fits it in-house across the Illawarra — we hoist the car, seat the hotdog and rear muffler and line up both 2.5in paths for clearance. Send your build and we'll confirm fit and book a bay.

Common questions
- Why choose the hotdog version over an all-muffler one?
- The hotdog is a straight-through resonator that breathes more openly than a chambered muffler, so this build has a touch more presence while the rear muffler still keeps it controlled.
- What size is the MKHN0303?
- It's a 2.5in dual cat-back — two 2.5in pipes for the Holden WK/WL Statesman V8.
- Is the catalytic converter retained?
- Yes. It's a cat-back, so it sits behind the factory catalytic converter and leaves it in place.
