This is the GTS-R-specific system: the MPI Automotive HOLK128-178-GTSR is a dual 3in full system with 1⅞in headers, listed to fit the Holden VF HSV GTS-R LSA V8 sedan. The LSA fitment and the larger 1⅞in primaries are what mark it out — this is the supercharged flagship's header set, not the non-LSA Commodore part.

Built for the LSA GTS-R sedan

What sets this SKU apart is the car it's listed for — the HSV GTS-R running the supercharged LSA V8 in the VF sedan. The LSA cars run different hardware to the naturally-aspirated Commodores, so a header set has to be the GTS-R-specific version to package correctly. This is that part, configured for the sedan body and its under-floor routing rather than a ute or wagon.

What do the 1⅞in primaries suit?

The 1⅞in headers here run a larger primary cross-section, giving exhaust gas more room to move. Bigger primaries generally favour a higher-output, higher-revving engine — which suits the character of a supercharged GTS-R — trading some low-down gas speed for top-end breathing. It's the bore that fits a flagship build rather than a stock-feel street tune.

What's in the full system?

It's a complete header-back package: tube-and-merge 1⅞in headers replacing the factory cast manifolds, then a mandrel-bent dual 3in run through the sedan. The 3in pipe opens the path the standard exhaust restricts. MPI Automotive publishes no material, muffler or tip detail for this listing, so we describe what's stated and leave the unstated specs out rather than guess at them.

Will it suit my GTS-R, and is it road legal?

It's listed to fit the Holden VF HSV GTS-R LSA V8 sedan; with no years or series published we confirm the match on the vehicle. Headers carry no cat or muffler in themselves, so registrability depends on how the full system is configured and approved against NSW requirements — which we work through for your car. Oak Flats Muffler Men fits these across the Illawarra; RRP is listed at 5776.53 AUD.
