Toyota Landcruiser HDJ78 4.2L Troop Carrier 3in Turbo Back With Hotdog.
Category: Mufflers and resonators


The MPI Automotive MKTY0029 is a 3in turbo-back exhaust for the HDJ78 4.2L Toyota Landcruiser Troop Carrier, finished with a hotdog resonator. The hotdog is the distinguishing feature — a compact straight-through silencer that keeps the system flowing freely from the turbo back with only light silencing.
A turbo-back replaces the exhaust from the turbo outlet rearward, the full span where the 4.2L turbo-diesel tends to free up most. A hotdog is a small straight-through resonator — gas passes through a perforated core, trimming a frequency without choking flow or adding length. On a Troopy that's the more open finish, suited to an owner who wants the system breathing freely and isn't chasing the quietest cabin.
At 3in, this turbo-back gives the 4.2L diesel a generous path from the turbo back. The material isn't published by MPI Automotive for this listing, so if stainless versus aluminised corrosion life matters on a hard-working Troop Carrier, confirm what's supplied with the workshop.
It's listed to fit the Toyota Landcruiser HDJ78 4.2L Troop Carrier. The cat status isn't published for this listing, so if road compliance matters for your build, ask the workshop to verify what the system retains. Confirm your exact vehicle too.
