The MPI Automotive MKHN0066SC is a 2.5in cat-back muffler system listed for the VP-to-VS Holden Commodore sedan, 5L V8 with independent rear suspension. It is one of MPI's IRS-sedan cat-back variants under the MKHN0066 family — confirm the exact variant code against your car with the workshop.

Why does the variant code matter?

MPI lists more than one cat-back under the MKHN0066 number for the IRS V8 sedan, separated by a suffix. The variants share the 2.5in bore, the muffler and the IRS sedan fitment but are not interchangeable line-for-line, so quoting the full code — MKHN0066SC — when you order is what gets the right pipework on your car. We confirm the suffix against your build before booking.

What does a 2.5in IRS cat-back cover?

This replaces the system from the catalytic-converter flange rearward — intermediate pipe, muffler and tailpipe — with the front section and cat left in place. The routing is shaped for the independent rear suspension on this V8 sedan. At 2.5in it is the mid-size bore, opening the rear of the run over a tired factory system while keeping the note muffled rather than open.

Will it suit my Commodore sedan?

It is listed to fit the VP, VR and VS Commodore sedan with the 5L V8 and IRS. Because both the series spread and the variant suffix matter here, confirm your exact model, year and rear suspension with the workshop before ordering rather than going by the badge.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits this IRS V8 cat-back in-house across the Illawarra. We check the variant code suits your car, confirm the independent-rear routing, inspect the cat flange and hangers, then mount it square. Send your model and year and we will confirm fitment and book the bay.

Common questions

How is the MKHN0066SC different from other MKHN0066 variants?
MPI lists more than one cat-back under the MKHN0066 number with different suffixes. They share the 2.5in bore and IRS sedan fitment but aren't interchangeable, so quote the full code when ordering.
Is it for the IRS sedan?
Yes — it is listed for the VP to VS 5L V8 sedan with independent rear suspension. Confirm your rear suspension with the workshop.
Does it keep the cat?
Yes — it is a cat-back, so the factory cat and front section stay in place.
