MPI Automotive Landcruiser GDJ79 Ute, 2.8L TD, 2023-Current, 3in Dual Turbo Back Without Cat & Without Muffler.
Category: Mufflers and resonators


No muffler, no resonator, no cat — the MPI Automotive MKTY0411 is the stripped-back 3in dual turbo-back for the Toyota LandCruiser GDJ79 Ute 2.8L (2023 on). It leads with flow: a straight-through path from the turbo to the tips, with nothing in the system to settle the note.
This MKTY0411 layout deletes the muffler entirely, so 3in dual pipe carries gas straight from the turbo outlet to the tailpipes with nothing to baffle the sound. It's the least restrictive of the GDJ79 turbo-back builds and the loudest, suited to owners chasing minimal back-pressure who have already decided how the ute will be used away from the bitumen.
The MKTY0411 is a turbo-back without the catalytic converter. Deleting the cat removes emissions hardware the GDJ79 left the factory with, so it is not ADR 79/04 compliant for road registration in NSW and is supplied for off-road and competition use only. We'll be upfront about that before you commit.
It's listed to fit the LandCruiser GDJ79 Ute 2.8L turbo-diesel from 2023; confirm the exact build with the workshop before ordering, since the feed can trail running changes. The MKTY0411 lists at $3,243.72 and is brought in to order as a turbo-back.
Oak Flats Muffler Men fits these dual systems on-site. With no muffler in the run, hanger isolation and clearance matter more — we set the system so resonance isn't transmitted into the cab, then check the dual-exit routing over the rear axle.
