The MPI Automotive MKHN0304 is a 2.5in dual cat-back for the Holden WK/WL Statesman V8, finishing in a muffler-and-tailpipe layout. The 2.5in bore marks it as the milder of the dual Statesman options — twin pipes sized for a standard or lightly worked V8.

What does the 2.5in dual layout suit?

At 2.5in this MKHN0304 keeps gas speed up for low-down response on a standard or lightly modified V8, rather than chasing top-end flow. Run as a dual cat-back, it splits into two 2.5in pipes from the catalytic converter rearward across the long-wheelbase Statesman floor. It's the keener-bore choice for an owner who wants the twin layout without stepping up to the larger pipe.

What does muffler-and-tailpipe mean?

The MKHN0304 silences through a muffler and then runs out to a tailpipe, so the note is chambered once before it exits rather than passed through multiple boxes. The absorptive muffler tempers resonance and drone for a civil road character on the Statesman. We can't quote a sound level; the honest measure is hearing a comparable WK/WL fit.

Will it suit my WK or WL Statesman?

It's listed to fit the Holden WK and WL Statesman V8. The long-wheelbase body and the V8 set the dual 2.5in routing. Confirm your exact build with the workshop before ordering, as these cars ran running changes.

How do we fit it in Illawarra?

Oak Flats Muffler Men supplies and fits the MKHN0304 in-house across the Illawarra. We match the twin 2.5in run to the hangers, check clearance along the long floor, and set the muffler and tailpipe square. Bring the car in and we'll confirm fitment and book the bay.
