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 DPF, to the tail, it’s has a pipe only configuration for maximum noise level under full throttle – with the DPF reducing sound inside the cab when under light throttle and cruising, ensuring no drone. The DPF back system has no mufflers at all, for maximum sound. We do classify it as a “quiet” noise level, due to the factory DPF still being in place a restricting a lot of noise, however there is a measurable increase in noise over the factory system, and a discernable seat of the pants power difference.
For offroad or race use, we have our turbo back exhaust options. These will need to be coupled with an ECU tune once the exhaust is fitted. The three noise level options are as follows:
- “Quiet” uses a high flow, oval muffler to keep noise levels as quiet as possible while maintaining maximum performance.
- “Medium” uses a hotdog resonator to give a full bodied V8 note, while taking the edge off the “thongslap” sound these engines are renowned for.
- “Loud” – our loudest option, no mufflers at all on this one!
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!
