Built as a 2.5in dual system with twin mufflers, the MPI Automotive SSMKHN0160 is listed for the HSV VZ GTO V8 Monaro. The dual-pipe, muffler-and-muffler layout is its signature - two 2.5in paths each ending in a chambered silencer, sized for the V8 coupe.

What does the 2.5in dual layout mean?

This SSMKHN0160 runs two 2.5in pipes rather than a single bore - a dual cat-back for the HSV VZ GTO Monaro V8. Splitting the flow into twin 2.5in paths is the configuration that sets it apart, matched to the V8 coupe's twin-outlet layout from the cat rearward.

What do the twin mufflers do?

The muffler-and-muffler spec puts a chambered silencer in each of the two runs, working by absorption and reflection. That gives a settled, controlled note for the GTO rather than an open or hotdog tail - the silencing choice that distinguishes it within the Monaro range. Two silencers, one per pipe, keep the coupe's note controlled rather than raw on the GTO.

What does a cat-back leave in place?

A cat-back replaces the exhaust from the catalytic converter back, so the factory cat stays upstream where HSV fitted it. On the VZ GTO this is the dual 2.5in run from the cat rearward through both mufflers - emissions hardware untouched.
