The MPI Automotive MKHN0066TC is a 2.5in cat-back muffler system for the VP-to-VS Holden Commodore sedan with the 5L V8 and independent rear suspension. It is the IRS-specific fitment: the rear routing is shaped for the independent rear end rather than a live axle.

What does the IRS fitment mean?

On a V8 Commodore sedan with independent rear suspension, the cat-back has to thread around the IRS cradle and the differently positioned mounting points, so the rear routing is specific to that car. The MKHN0066TC is listed for the IRS sedan, which is why getting the right part for your rear end matters — a live-axle pipe will not sit cleanly under an IRS car. It runs at a 2.5in bore through a muffler to keep the note controlled.

What does a 2.5in cat-back cover?

Cat-back means everything from the catalytic-converter flange back is renewed — intermediate pipe, muffler and tailpipe — while the front section and the cat stay as fitted. At 2.5in it is the mid-size bore, freeing the rear of the system over a restrictive or tired factory run while keeping gas speed sensible for a street V8. The muffler keeps the cruise note in check.

Will it suit my VP-VS Commodore sedan?

It is listed to fit the VP, VR and VS Commodore sedan with the 5L V8 and IRS. That spans several series, and the IRS detail is the one that catches people out, so confirm your exact model, year and rear suspension with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits this IRS cat-back in-house across the Illawarra. We confirm the car is the independent-rear version, check the cat flange and the hanger points around the IRS cradle, then mount it square. Send your model and year and we will confirm fitment and book the bay.
