HSV VE E3 Sedan Wagon 3in Catback Hotdog/Muffler.
Category: Mufflers and resonators


The MPI Automotive MKHN0187 is a 3in cat-back for the HSV VE E3 sedan and wagon, pairing a hotdog resonator with a rear muffler. The hotdog trims drone up the line while the rear muffler sets the note — a two-stage layout on the larger bore.
A hotdog is a compact straight-through resonator: exhaust passes through a perforated core rather than around baffles, so it cuts a target drone frequency without choking flow. On the VE E3 it sits ahead of the rear muffler, taking the harshness out of mid-range resonance through the cabin floor before the rear box finishes the job. It's the stage that keeps a 3in system liveable on the highway.
Three inches is the larger pipe option, sized for an engine that wants room to breathe rather than the tighter stock-style tube. Paired with the hotdog-and-muffler layout, the MKHN0187 flows freely but keeps two silencing stages in the line — not a stripped, single-box setup. We won't quote a sound level; a comparable fit is the honest gauge.
It's listed to fit the HSV VE E3 in sedan and wagon body. The wagon's longer rear floor routes differently from the sedan, and this system covers both; confirm your exact build with the workshop before ordering. It's a cat-back, so the catalytic converter and front pipework are retained.
Oak Flats Muffler Men supplies and fits the MKHN0187 in-house across the Illawarra. We set the hotdog and rear muffler on the car's hangers, check clearance to the floor and rear valance, and join each stage square to the pipe. Bring the car in and we'll confirm fitment and book the bay.
