For Hainzy - I had the VN 5.0 with supra 5 and the aussi 4 fitted with the factory VQ statesman style extractors. you just need to plug the o2 sensor hole because the sensor doesn't fit in that spot, weld another sensor mount on a different angle. then had a new system built from there back. I'll possibly be selling my complete old system if I can sort out a new system.
