Isuzu D-Max Jan 2017 - 2020 3.0L TURBO BACK WITH CAT & WITHOUT MUFFLER (MKIZ0027) Fits ISUZU. Fast.
Category: Mufflers and resonators


Running straight through at the rear with no muffler and no resonator is what marks out the MPI Automotive MKIZ0027 — a with-cat turbo-back for the Isuzu D-Max 3.0L (2017–2020) that keeps the catalytic converter but leaves the back of the system completely open.
Where other builds in this range tuck a resonator or muffler into the rear, the MKIZ0027 deletes both — nothing sits between the cat and the tailpipe to soften the note. That makes it the most vocal of the with-cat turbo-backs here, with the rawest character the layout allows while the cat is still in place. It's the pick for an owner who wants the open sound rather than a managed, drone-trimmed one.
The system replaces the exhaust from the turbo outlet rearward, a longer span than a cat-back, and that's where a 3.0L diesel tends to free up. The catalytic converter is retained, so the D-Max keeps the emissions hardware it left the factory with — the deciding factor for diesel-ute road compliance — even though the rear runs open.
Because the catalytic converter stays in place, the MKIZ0027 retains the factory emissions equipment rather than removing it. Noise limits and any state requirements still apply with an open rear, so confirm the exact build and what's permissible in your state with the workshop before fitting.
