The MPI Automotive HOLK128-134-GTSR is a dual 3in full exhaust system with 1-3/4in headers listed to fit the Holden VF HSV GTS-R V8 (LSA supercharged) sedan. It's a complete header-back package — the headers and the full 3in run behind them, not a rear-section swap.

What's a full headers system and what does it change?

Tubular headers replace the cast factory manifolds so each cylinder feeds a longer, more even tube into the collector instead of a shared casting. This is the full-system version: 1-3/4in primaries up front, then dual 3in pipe all the way back. A full tube-header system on a V8 breathes more freely and changes the note versus stock, but it's a larger install than a bolt-on rear muffler. No power, weight or sound figures are published by the supplier, so none are quoted.

Will it suit my Holden VF HSV GTS-R?

It's listed to fit the Holden VF HSV GTS-R V8 (LSA supercharged) sedan. This is the LSA (supercharged) version, so the front-end routing is specific to that engine. The listing names HSV models, so it's the HSV-bodied car rather than a base Commodore. Treat the fitment as listed-to-fit, not guaranteed: confirm your exact model (GTS-R), engine and body with the workshop before ordering the 3in package.

Is it road legal?

A full headers-back system sits between your V8 and registration in NSW, so road compliance comes down to the complete setup and how it's tuned. This listing doesn't state whether a catalytic converter is included, so we won't claim it either way. If you need the car road-registered, tell us up front and we'll work through what your build requires.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits full systems like the HOLK128-134-GTSR in-house across the Illawarra. A header-back install on a V8 VF means working tight around the engine and driveline, so we check clearances, set the dual 3in run, and hang it on fresh mounts. It's listed at $5639.93 and is an item we confirm and order in for your specific car — send your build and we'll book the bay.
