At a full 3in in a dual layout, the MPI Automotive SSMKHN0120 is the largest-bore cat-back in this Commodore sedan group - listed for the Holden Commodore VT-VZ V8 Sedan with twin mufflers. The 3in dual routing is the headline: two larger-diameter pipes for the V8, each ending in a chambered silencer.

What does a 3in dual suit on the VT-VZ V8?

Bore and routing lead here. This SSMKHN0120 runs two 3in pipes - the larger diameter in a dual layout - for the VT-VZ Commodore V8 Sedan. It's the most generously-sized of the sedan cat-backs, giving the gas room from the cat back through two paths, suited to a bigger-output or modified V8.

What do the twin mufflers do?

The muffler-and-muffler configuration places a chambered silencer in each run, quietening by absorption and reflection. On a 3in dual that keeps the note settled despite the larger bore - the silencing choice that distinguishes it from a hotdog or single-muffler build. Two silencers keep the note settled despite the larger 3in bore, which would otherwise read louder.

What does a cat-back leave in place?

A cat-back replaces the exhaust from the catalytic converter rearward, leaving the factory cat upstream. On the VT-VZ sedan that's the dual 3in run from the cat back through both mufflers - the emissions hardware untouched.

Will it suit my VT-VZ sedan?

It's listed for the Holden Commodore VT-VZ V8 Sedan. Oak Flats Muffler Men supplies and fits 3in dual cat-backs in-house across the Illawarra - send your exact build so we can confirm fitment before ordering. As an MPI Automotive special-order part, we confirm the build and lead time with you before ordering rather than holding it in stock.
