The cats on the DE appear to be in great shape.
I think that they are OEM with the heatshields removed.
Unsure when I am going to start to dismantle this car, so if you require these tomorrow than that is not going to happen I am afraid.
Alex.
I just took another low mileage 350z DE in for dismantling today so should be able to help you with DE cats.
I will get it on the ramp on Monday and let you know.
Well, if they can not hook your coils up in the correct order, then I would be looking at the spark plugs (wrong type, wrong gap) and also all the 3 pins in each coil in case they have bent or damaged them.
