Isuzu D-Max 2020 ON 3.0L TURBO BACK WITH CAT & WITHOUT MUFFLER (SSMKIZ0022) Fits ISUZU. Fast shipping.
Category: Mufflers and resonators


Retaining the catalytic converter while deleting the muffler, the MPI Automotive SSMKIZ0022 is the with-cat, no-muffler turbo-back for the 2020-on Isuzu D-Max 3.0L. Keeping the cat across a full turbo-back span while running muffler-free is what sets it apart.
A turbo-back replaces the exhaust from the turbo outlet back — a longer span than a cat-back, where a 3.0L diesel breathes better. This version retains the catalytic converter through that span but deletes the muffler, so the note is more direct than a muffler-equipped run while the converter stays in place. It's the freer-sounding of the with-cat options for the 2020-on D-Max.
Because the SSMKIZ0022 retains the catalytic converter, it keeps the diesel emissions converter the D-Max left the factory with — the central item for road compliance on these utes. The muffler-delete does affect noise levels, so confirm your state's noise requirements and the exact build with the workshop before fitting.
This layout suits owners who want the harder, freer note of a muffler-delete while keeping the emissions converter in place. It's the configuration that balances a more vocal turbo-back against retaining the cat, rather than a full delete.
