    How many are there? Ive done alot of searching and some people say 3 and some say to. I devlive there is a small pre one just after the turbo then the exhaust drops under the car into a rather large exhaust box, is this the main DPF? Or is that just a normal silencer?

    I think its a pre-cat after the turbo, then two cats, one on each side of exhaust if its standard dual exit.

    Yes I agree there is no DPF, just only catalysts on the 2.5 cab.
