The MPI Automotive HOLK128-178-GTS is a 3in full exhaust system with 1-7/8in tubular headers listed to fit the Holden HSV GTS sedan and wagon 6.2L V8 (LSA). It runs dual 3in piping from the headers all the way back, so it’s a header-back system rather than a tailpipe-only change.

What’s a full header-back system and what does it change?

This is a full system: tubular headers (1-7/8in primaries) replace the cast factory manifolds at the front, then dual 3in pipework carries the lot rearward. Replacing the manifolds with tube headers gives each cylinder a longer, more even path into the collector instead of a shared casting, which breathes more freely and changes the note compared with stock. It’s a header-back job, not a tailpipe swap. No power, weight or sound figures are published by the supplier, so none are quoted here.

Will it suit my Holden HSV?

It’s listed to fit the Holden HSV GTS sedan and wagon 6.2L V8 (LSA). This is a VF-era HSV listing, the LSA-engined version. Treat fitment as listed-to-fit, not guaranteed: confirm the body type, rear end and engine with the workshop before ordering the 3in package.

Is it road legal?

Headers and the pipework behind them sit between your car and registration in NSW, so road compliance comes down to the complete system and how it’s set up. This listing doesn’t state whether a catalytic converter is included, so we won’t claim it either way. If road registration matters for your sedan, raise it with us first and we’ll talk through what your build needs.
