The 1VD V8 4.5L common rail turbo diesel engine in the current 70 Series Landcruiser has forged itself a reputation as a tough off-roader, with truck-like power and a fantastic amount of torque right from the word go. Off the factory floor, the Landcruiser is shackled by the very restrictive standard Toyota exhaust.
With the standard exhaust going as small as 1 & 7/8″, and running through a diesel particulate filter (DPF) and baffled muffler, the sound of the V8 motor is nowhere to be heard. The fitment of a Manta 3″ exhaust system changes all that! Running full 3″ piping, right from the either the turbo face or the DPF, to the tail, it’s available in a number of configurations, so you can have an exhaust note close to the factory level, go all out with a wild, unmuffled V8 bark, or find a happy medium somewhere in between.
For the ultimate in looks and sound, we now also have our twin 3″ tailpipe version available. If you’ve already got a Manta exhaust, this is available as a simple bolt-on to your existing exhaust system!
Replacing the standard exhaust with a 3″ version has a number of benefits, including reduced turbo lag, improved peak power and torque, greater responsiveness, and reduced fuel consumption. On average, we see a 15% gain in power, and around 1 – 2L per 100km reduction in fuel consumption (with a full exhaust and tune).
The full 3″ exhaust is consistently rated as the best performance modification to carry out on the V8 Landcruiser, not only due to the glorious sound it releases but also for the massive improvement in driveability. Many dealers are fitting them on brand new vehicles – don’t spend another day without one!
DPF BACK OR TURBO BACK?
The latest model Landcruiser comes from the factory with a Diesel Particulate Filter. These are an emissions device designed to control the amount of soot emitted from the exhaust system. We have two options in our exhaust range – DPF back (similar to a “cat back” system on a petrol vehicle), or turbo back (replacing the entire factory exhaust system, including the DPF).
The turbo back system does require a recalibration of the vehicle’s Engine Control Unit (ECU) to remove certain functions associated with the DPF system. This is intended for off-road or race use only.
In the future, we plan to introduce a high flow DPF system which will give you the benefits of a performance exhaust system while ensuring compliance with road rules.
