Hi all,

I have a question regarding how many cats there are on the 2.7 v6?

I know there is 1 under the car in the main exhaust pipe but is there 2 other cats hidden somewhere as i've been told there could be 3.

Thanks in advance.

I don't know if the exhaust configuration is the same in Europe as in the USA. Mine has 3, one each immediately after the front and rear exhaust manifolds and the one under the truck. The ones after the manifolds you will see 2 oxygen sensors, one before the catalytic and one immediately after. You can't miss the catalytic in the front. If you look down between the radiator and the engine it is covered with a heat shield.
