The MPI Automotive SSMKHN0255 is a 2.5in extractor-and-pipe package listed to fit the Holden Commodore VY/VZ V8 1 Tonner. It pairs extractors at the heads with a dual pipe layout and no rear muffler, for a straighter-through, louder layout.

What does this system cover?

This part number is an extractor-back package: it starts at the extractors on the cylinder heads and carries 2.5in pipework rearward, running straight through with no rear muffler. It is set up as a dual system. It is one of 3 concrete fitments recorded for this part.

What are extractors and what do they change?

Extractors, also called tuned headers, replace the cast factory exhaust manifolds with separate equal-length tubes that merge further downstream. The point is to cut the back-pressure a shared cast manifold creates, so the gases leaving one cylinder interfere less with the next. On a V8 such as this one that typically reads as a freer-breathing top end and a harder exhaust note than stock; the trade-offs are more underbonnet heat and a job that is a proper workshop fit rather than a bolt-on muffler swap.

Will it suit my Holden V8?

Listed fitment is the Holden Commodore VY/VZ V8 1 Tonner. The 1 Tonner is the cab-chassis body, which sits apart from the wellside ute. Holden ran several series and body styles across this family, and small differences in mounts and tailpipe routing matter. Treat it as listed to fit and confirm your exact Holden build with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Fitting happens at our Oak Flats workshop in the Illawarra, where extractor jobs want a hoist, fresh gaskets and time to dress the runners in. With no rear muffler this is the louder choice in the range. It carries a recommended retail price of $4,715.67 and is typically a special-order item. Send us your exact Holden build and we will check clearances before it is ordered.
