The MPI Automotive MKHN0423 is a 3in extractor-and-exhaust package on 1-3/4in primary extractors, listed to fit the Holden Commodore VE V8 in sedan and wagon body styles. It runs a hotdog resonator into a rear muffler, so it's a header-back overhaul rather than a tailpipe swap.

What does this extractor system cover?

This is a header-back package for the VE Commodore V8. It starts at the cylinder heads with 1-3/4in primary extractors and carries a 3in exhaust through a hotdog resonator into a rear muffler. The factory cast manifolds and original pipework both come out, replaced as one matched MKHN0423 kit. The hotdog-plus-muffler layout trims resonance while opening the V8 up compared with the restrictive stock manifolds.

What's an extractor and what does it change?

Extractors are tuned-length headers that replace the cast manifolds the V8 ships with. Giving each cylinder its own primary tube before the merge lowers back-pressure and helps the engine scavenge spent gas. The honest trade-offs are heat exposure in the bay, a longer fit than a bolt-on muffler, and a changed note versus stock. The 1-3/4in primaries here are matched to the 3in downstream pipe so the system flows as one set across the sedan and wagon.

Will it suit my Holden Commodore VE?

It's listed to fit the Holden Commodore VE V8 in sedan and wagon form. Because an extractor system is tied to the specific body and driveline, the exact build matters: send your VE details and the workshop will confirm fitment before anything is ordered.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits MPI extractor packages like the MKHN0423 in-house across the Illawarra. The job means pulling the factory manifolds, fitting the primaries, then hanging the 3in hotdog-and-muffler run and checking clearances down the floor. At an RRP of $4,676 it's a special-order set, so we confirm fitment and lead time with you before booking the bay.
