Listed for the IRS-equipped sedan, the MPI Automotive MKHN0058 is a 2.5in cat-back muffler for the 5L V8 Holden Commodore VP, VR and VS. The independent-rear-suspension body sets the rear routing this system is shaped around.

Why does IRS matter here?

The independent rear suspension on these sedans changes the geometry behind the diff, so a cat-back has to be routed and clearanced for that body specifically — it isn't interchangeable with a live-axle car. The MKHN0058 is shaped for the IRS VP–VS sedan, with a 2.5in bore matched to the 5L V8 for flow without losing mid-range gas speed.

What does the cat-back cover?

Cat-back means everything from the catalytic converter back to the tail, leaving the engine's emissions hardware untouched. The muffler quietens by absorbing and reflecting sound inside its body. On a V8 the 2.5in bore is the sensible street size. We can't quote a sound level — hearing a comparable fit is the honest measure.

Will it suit my VP–VS V8 sedan?

It's listed to fit the 5L V8 Commodore VP, VR and VS sedan with IRS. Because the rear suspension type governs the fit, confirm your car runs IRS and check the exact build with the workshop before ordering.

How is it fitted in Illawarra?

Oak Flats Muffler Men supplies and fits the MKHN0058 in-house across the Illawarra. We match it to the cat flange, check clearance around the IRS cradle, and hang the muffler square. Bring the sedan in and we'll confirm fitment.
