Holden Colorado 7 SUV 2.8L TURBO BACK WITH CAT & CENTRE HOTDOG.
Category: Mufflers and resonators


The MPI Automotive SSMKHN0473 is a turbo-back for the 2.8L Holden Colorado 7 SUV that keeps the catalytic converter and runs a centre hotdog — the cat-retained build with a compact mid-chassis resonator. It is listed to fit the Colorado 7 SUV 2.8L.
The centre hotdog is a straight-through resonator mounted mid-chassis where the wagon would carry a centre muffler. It softens the harshest frequencies without the bulk of a chambered box, so the SSMKHN0473 keeps the Colorado 7 freer-flowing than a centre-muffler build while staying more contained than an open centre section.
This is the with-cat layout, so the catalytic converter stays and the factory emissions hardware the wagon came with is retained — for owners who want the hotdog character without deleting the cat.
Because it keeps the catalytic converter, the SSMKHN0473 leaves the factory emissions equipment in place. Confirm the exact build and any state requirements with the workshop before fitting.
Oak Flats Muffler Men supplies and fits turbo-back systems in-house. It is listed to fit the 2.8L Colorado 7 SUV; we confirm the centre hotdog placement and tunnel clearance before booking.
The SSMKHN0473 is an MPI Automotive supplier system at a listed RRP, brought in once fitment is confirmed. Diameter and material aren't published in the record, so we don't quote figures we can't verify — instead we check the cat position, the turbo flange and the centre hotdog mounting against your 2.8L Colorado 7 wagon before placing the order.
