Holden Commodore VT 5L Sedan 2.5in Dual With Extractors Hotdog/Muffler.
Category: Extractors and headers


The MPI Automotive SSMKHN0113 pairs a hotdog resonator with a rear muffler on a 2.5in dual layout for the 5L VT Commodore sedan. That two-stage silencing is its defining trait — a header-back system tuned to take the rasp off without going fully quiet.
Rather than one muffler or two of the same, the SSMKHN0113 runs a hotdog resonator up front and a rear muffler behind it across its 2.5in dual pipework. The hotdog knocks down the harsher mid-range rasp a worked V8 makes, while the rear muffler handles the bulk of the silencing. The result on the 5L VT is a cleaner tone than a single-muffler build without the drone of a fully boxed-in twin-muffler setup.
It's a header-back system for the 5L VT sedan: tuned-length extractors at the cylinder heads, dual 2.5in pipework, the hotdog resonator and the rear muffler. The factory cast manifolds and the original exhaust both come out and the SSMKHN0113 goes in as one matched set, with primaries sized to the 2.5in legs so the whole run flows together.
Extractors are tuned-length headers that replace the restrictive cast manifolds the VT's 5L left the factory with. Each cylinder gets its own primary tube before the merge, cutting back-pressure and helping the engine scavenge spent gas. Honestly stated, they sit in the engine-bay heat zone, take real labour to fit, and change the note — here softened and tidied by the hotdog-plus-muffler combination rather than left raw.
It's listed to fit the 5L VT Commodore sedan; send your build and Oak Flats Muffler Men will confirm it before ordering. Fitting at our Illawarra workshop means removing the factory manifolds, hanging the extractors, then routing the dual 2.5in pipework through the hotdog and rear muffler with clearance checks underneath. At an RRP of $4,531.08 it's a special-order set, so we confirm fitment and lead time first.
