Holden Colorado 7 SUV 2.8L TURBO BACK WITHOUT CAT & WITH CENTRE HOTDOG.
Category: Mufflers and resonators


The MPI Automotive MKHN0475 pairs a cat-delete with a centre hotdog on the 2.8L Holden Colorado 7 SUV. The hotdog is the distinguishing piece: a compact straight-through resonator that knocks the harshness off a free-flowing turbo-back without the bulk or volume drop of a full muffler. With the cat gone, it's an off-road build.
A hotdog is a short, straight-through resonator — gas passes through a perforated core rather than being bounced through chambers. On the MKHN0475 it sits in the centre of the run where a larger muffler would, so it takes the edge off drone and harshness while keeping the path open. The result is freer-flowing than a fully muffled system but more tempered than a straight pipe — the middle ground for a Colorado 7 owner who deletes the cat but doesn't want bare resonance.
No. It deletes the catalytic converter on a road-relevant turbo-back, so it is not ADR 79/04 compliant for road registration in NSW and is supplied for off-road use only. There's no softening that — the hotdog tames the note, but it doesn't change the cat-delete status. For a registrable wagon, choose a with-cat version.
A turbo-back replaces the exhaust from the turbo outlet rearward, the longest span short of a full custom system, and on a 2.8L diesel it's where the most pipework frees up. The MKHN0475 has a published RRP of $1,407.55.
Oak Flats Muffler Men supplies and fits MPI turbo-back systems in-house across the Illawarra. It's listed to fit the Colorado 7 SUV; because it's an off-road cat-delete we'll confirm where it can be used, then check hotdog placement and clearances on the hoist before fitting.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
