MPI Automotive's MKHN0144 is a 2.5in extractor-back system listed to fit the Holden VX VY V8 Monaro, running headers from the heads through to a muffler and tailpipe. It is a full kit, not a back-box change.

What's in the kit?

The kit covers the Holden VX VY V8 Monaro from the heads back — extractors, the mid pipes, and a rear section that gives you a muffler then a tailpipe at the rear. Pipe size is listed at 2.5in. It runs a dual layout.

What do extractors actually do?

An extractor set replaces the factory cast manifolds with equal-ish length tubes that each carry one cylinder's pulse before merging. Less restriction off the heads is the goal, and on an older performance car that is where owners chase a freer-breathing result and a fuller note. It is not a free lunch: headers are fiddly to fit around steering and chassis, they alter how the car sounds, and they sit in the part of the system the regulator cares about — so legality is a per-car question, not a blanket one.

Does it fit my Holden?

Listed to fit the Holden VX VY V8 Monaro, this one needs your exact variant confirmed first. Listing data is not infallible and these models ran across a few variants, so treat the fitment as listed-to-fit rather than confirmed for your exact car. Send your details through and our Oak Flats workshop in the Illawarra will check them against the listing before placing the order.

Is this road legal?

Because extractors replace emissions-relevant hardware at the front of the system, whether the result is acceptable for road registration in NSW depends on the individual vehicle and inspection. No blanket compliance is published for this part by MPI Automotive, and we will not claim one — talk it through before committing.
