Isuzu D-Max 2020 ON 3.0L TURBO BACK WITHOUT CAT & WITH MUFFLER (SKU: SSMKIZ0023) Engineered. Quality guaranteed.
Category: Mufflers and resonators


The MPI Automotive SSMKIZ0023 is a turbo-back for the 2020-on 3.0L Isuzu D-Max that deletes the cat but finishes through a rear muffler — the quieter of the cat-delete builds. It is listed to fit the D-Max 3.0L from 2020.
A chambered rear muffler reflects and absorbs exhaust pulses, so the SSMKIZ0023 is the most subdued of the cat-delete turbo-backs for this D-Max. It keeps the diesel note liveable on the highway while still opening the system up over the factory layout — the muffler version for owners who want a deeper tone without the bark of a hotdog or open build.
It replaces the exhaust from the turbo outlet rearward, the full span on the 3.0L. This is the without-cat configuration, so the catalytic converter is removed.
Because it removes the catalytic converter, it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road or competition use only.
Oak Flats Muffler Men supplies and fits turbo-back systems in-house. It is listed to fit the 2020-on 3.0L D-Max; we confirm clearances and hangers before booking the bay.
The SSMKIZ0023 is an MPI Automotive supplier system at a listed RRP, brought in once we've confirmed it suits your truck. Diameter and material aren't published in the record, so we verify the spec against your actual ute rather than assume — checking the turbo flange, the muffler location and the tailpipe exit on your 2020-on 3.0L D-Max before placing the order.
