The MPI Automotive FX-298 is a tuned extractor listed to fit the Holden Commodore VT to VZ with the Gen III V8 in 5.7L or 6.0L. It runs 1-3/4in primaries in a 4-into-1 layout with a 3in 2-bolt outlet.

What does this extractor cover?

This is the header for the Gen III V8 Commodore from VT through VZ, in either 5.7L or 6.0L. It uses 1-3/4in primary tubes merged 4-into-1, finishing in a 3in outlet with a 2-bolt flange. The 2-bolt outlet matters because it's the join you'll pipe the rest of the system to, and it sets how it mates to your existing exhaust or a new cat-back. This is the extractor section only — it replaces the factory manifolds, not the whole system.

What is a tuned 4-into-1 extractor and what does it change?

A tuned 4-into-1 extractor sets each of the four primary pipes per bank to a chosen length so the cylinders' pulses meet at one collector in a deliberate rhythm, rather than dumping into the short cast log the factory used. On a Gen III V8 like this, that swap is where the airflow gain over the standard manifolds sits. The 1-3/4in primary size is matched to these engines. Because tubular headers sit closer in the bay than cast iron, clearance against steering and chassis is checked when fitting.

Will it suit my VT-VZ Commodore?

It's listed to fit the Holden Commodore VT, VX, VU, VY and VZ with the Gen III V8 in 5.7L or 6.0L. Years aren't published beyond those body codes, so send us your build and we'll confirm the FX-298 matches the engine and outlet you're running before ordering. We treat the listing as 'listed to fit', not a guarantee.
