MPI Automotive Toyota GDJ251R Prado, 2.8L TD 2024 On, 3in Turbo Back Without Muffler Without Cat.
Category: Mufflers and resonators


The MPI Automotive SSMKTY0505 is a stainless 3in turbo-back system, no muffler and no cat, listed to fit the Toyota Prado GDJ251R 2.8L turbo-diesel from 2024 on. Deleting the cat is the defining choice here: this is the most open, least restricted build in the range, and that comes with a hard road-legality caveat.
No. Because the SSMKTY0505 removes the catalytic converter on a turbo-back diesel system, it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only. There's no softening that — deleting the cat takes out the emissions hardware the Prado left the factory with, so it's intended for competition or off-road vehicles, not a registered daily.
Turbo-back means the system is replaced from the turbo outlet rearward — a longer span than a cat-back. Running 3in with no cat and no muffler, this is the freest-flowing version: nothing in the path to restrict or quieten it, so it's the loudest, most open build of the family. On the 2.8L turbo-diesel it's the choice for an off-road Prado where flow and a hard note matter more than refinement.
It's listed to fit the Toyota Prado GDJ251R 2.8L from 2024 on. Send your exact build and we'll confirm the fitment, tailpipe routing and whether this off-road-only spec is right for how the vehicle is used before ordering.
