yes,mine are in Sydney.Should be at my place Thursday.However,I went to Sydney and changed the twin catalytic converters for high flow sports ones and it has absolutely changed the car.I did a before and after dyno test,128.4KW at the wheels before and 2 hours later after the installation 136.9KW at the wheels and that is with the rest of the system still standard.That is equivalent to 13KW engine power increase(assuming 35% transmission losses).The torque was not recorded but that is what I noticed,the car now pulls like a train!There must be at least 15% more torque.
