Built for the 5L VT Commodore sedan, the MPI Automotive SSMKHN0114 runs 2.5in dual pipework with a single muffler and tailpipe — a header-back system that keeps the twin-leg routing but lets the back end breathe more openly than a twin-muffler build.
What's the dual 2.5in with muffler-and-tailpipe layout for?
This SSMKHN0114 keeps the V8 split into two 2.5in legs but carries a single muffler and a tailpipe rather than a muffler in each line. That gives the 5L VT a balanced result: the dual routing's even flow off each bank, with less silencing hardware than a two-muffler version, so the note sits a touch firmer. It suits an owner who wants the twin-pipe look and breathing without the fullest quiet build.
What does the system replace?
It's a header-back package for the 5L VT: tuned-length extractors at the heads, dual 2.5in pipework, one muffler and the tailpipe. The factory cast manifolds and the original exhaust come out together and the SSMKHN0114 goes in as one matched set, primaries sized to the 2.5in legs so it flows as a system rather than mismatched parts.
What's an extractor and what's the trade-off?
Extractors replace the restrictive cast manifolds the VT's 5L wore from the factory, giving each cylinder its own primary tube before the merge to cut back-pressure and improve scavenging. Be clear-eyed about the cost: they sit in the engine-bay heat zone, take longer to fit than a bolt-on, and change the note. On this build the single-muffler-plus-tailpipe choice lands the sound between the quietest and the loudest options.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits MPI extractor systems like this across the Illawarra. The work means pulling the factory manifolds, hanging the extractors, then routing the dual 2.5in legs into the muffler and tailpipe with clearance checks along the floor and over the axle. It's listed to fit the 5L VT Commodore sedan; at an RRP of $4,572.05 it's a special-order set, so we confirm your exact build and lead time before booking the bay.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Will the SSMKHN0114 fit my VT Commodore?
- It's listed to fit the 5L VT Commodore sedan. Confirm your exact build with the workshop before ordering, as extractor systems are tied to the specific body and driveline.
- How does this compare to a twin-muffler version?
- This one runs dual 2.5in pipework but only a single muffler with a tailpipe, so it carries less silencing and a slightly firmer note than a two-muffler layout. We have no measured sound figures to quote.
- Is it the full back end or just headers?
- It's a header-back system: extractors plus dual 2.5in pipework, a muffler and a tailpipe, supplied as one matched SSMKHN0114 kit.
