The MPI Automotive SSMKHN0122 is a 3in single extractor-and-exhaust package listed to fit the Holden Commodore VT-VZ V8 Sedan. It runs tubular extractors into a single 3in system with a muffler-and-muffler rear arrangement.

What does the SSMKHN0122 cover?

This is an engine-back build for the VT to VZ Commodore V8 Sedans. Tubular extractors replace the cast manifolds at the heads, then a single 3in pipe carries the gas rearward through a twin-muffler arrangement. Unlike the dual versions in the same range, this one merges to a single 3in run behind the extractors.

What's the difference between a single and dual 3in system?

A single system merges both cylinder banks into one 3in pipe after the extractors, where a dual system keeps two separate pipes running rearward. The single layout is simpler to route and still a substantial 3in bore, while the twin mufflers on this build add silencing capacity to keep the note contained. The extractors themselves replace the cast manifolds to ease back-pressure at the heads. The honest trade-off with any header-led system is that it's a heavier fit than a bolt-on rear section, which is why the run is supplied complete and sized to match the extractors.

Will it suit my VT to VZ Commodore?

It is listed to fit the Holden Commodore VT-VZ V8 Sedan across that generation. The single 3in run with twin mufflers is the choice where a single-pipe layout is preferred over a dual setup. Build details vary across VT through VZ, so confirm your exact Commodore specification with the workshop before ordering.
