The MPI Automotive SSMKHN0304 is a 2.5in dual cat-back for the Holden WK and WL Statesman V8, finishing through a muffler to the tailpipe. The 2.5in twin-pipe bore is the more restrained option for the long-wheelbase Statesman.

What does the 2.5in dual bore suit?

At 2.5in per pipe, this dual cat-back is the tighter-bore choice — twin pipes that keep gas speed up for a more street-focused, restrained character rather than the freer flow of a larger bore. On the WK/WL Statesman V8 that suits an owner after a tidy upgrade over standard without chasing maximum flow.

What does the muffler-to-tailpipe layout do?

The SSMKHN0304 runs a muffler into the tailpipe at the rear, so the note stays silenced through to the exit. Combined with the 2.5in dual pipes it's the more subdued of the Statesman cat-back options, keeping the V8 present but managed.

Will it suit my WK or WL Statesman V8?

It's listed to fit the Holden WK and WL Statesman V8 — the long-wheelbase models that share this dual routing. Confirm your exact build with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits dual cat-back systems like this across the Illawarra. We confirm the Statesman fitment, check both pipes for clearance, then book the bay. As an MPI part it can be special-ordered if it isn't in stock, and we'll confirm the current price and lead time when you book so the job is clear before work starts. If you're weighing this up against the larger-bore Statesman option, we can walk through which suits how you drive the car.
