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


The MPI Automotive MKTY0412 finishes its 3in dual turbo-back run through a hotdog resonator rather than a full chambered muffler — a compact straight-through unit that trims drone while keeping the system free-flowing. It's listed to fit the Toyota LandCruiser GDJ79 Ute 2.8L (2023 on).
A hotdog is a short straight-through resonator: gas passes through a perforated core wrapped in packing, so it takes the edge off resonance without the back-pressure of a baffled muffler. On the MKTY0412 that means a turbo-diesel note that's present and a touch firmer than stock, but settled enough to live with on the highway. It sits in a 3in dual layout sized to the GDJ79's 2.8L, with the resonator doing the work a full chambered muffler would otherwise handle.
This is a turbo-back configuration without the catalytic converter, so it removes emissions hardware the GDJ79 left the factory with. As supplied it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road and competition use only. Talk to us about your registration situation before committing — we won't soften that position to make a sale.
It's listed to fit the LandCruiser GDJ79 Ute 2.8L turbo-diesel from 2023; confirm your exact build with the workshop, since feed data can lag running changes. The MKTY0412 carries an RRP of $3,300.77, and being a turbo-back it's a special-order item we bring in to suit your ute rather than a shelf part.
