The HDJ78 Landcruiser troop carrier, powered by the 1HD-FTE 4.2L turbo diesel, can easily be enhanced through the fitment of a high-flow Manta 3″ mandrel bent exhaust system. In fact, it’s probably the best performance modification you can do to this vehicle. The restrictive nature of the standard exhaust system, which runs as small as 2” piping, effectively chokes the motor.
By replacing the standard exhaust with a 3” mandrel bent pipe there are numerous benefits realised; including improved low-down torque and responsiveness, reduced turbo lag, reduced fuel consumption, and improved peak power.
Whether you’re towing a caravan, off-roading, or driving cross-country, the extra power from a Manta 3” exhaust is something you can’t do without.
With 3 configurations available, you can either keep the noise level close to stock, get a little bit of a note emanating from the 3” rear pipe, or go all out and get a loud, truck-like sound, with a lot of turbo whistle.
For an exhaust system that will last forever, you can get it in stainless steel – carrying a 10 year warranty, or we also have it in aluminised steel, with a 2 year warranty. The entire system is designed for easy fitment, using factory mounting points.
This system will also fit a HZJ75, if a Toyota CT26 turbo (the 1HD factory turbo) setup is fitted aftermarket.
The system shown in the video is the medium noise level.
