Hi, Sorry to butt in on your thread, but why are you fitting the 3.0 down pipes? Are they different to the 3.2's?

You want to keep 3.2 ones, they are better flowing.

Assume codes are P420's?

You need to move the pre-cat sensors  :y

Manifolds, yes.

Downpipes and cats... 3.0 are better ;)

Plenty on Ebay. It's a standard M18x1.5 sensor, IIRC. Ideally get a mild steel one.

I do wonder if one of these would resolve the cat efficiency codes, though... www.ebay.co.uk/itm/230712006719

That's an interesting thought actually :-\ I understand the theory of it getting the sensor out of the flow but... :-\
