    Right i have just decided i am going to buy a raceland 4-2-1 for my VTR which will obviosuly de-cat it, but i will buy a centre section to sort that.

    I know that the lambda sensor that goes in the bottom is the one which will be sleeved up, or the one which will read the clean air.

    But the one that reads the dirty air, where will that go as it looks as if there isn't a hole on the top of the raceland mani, only on the bottom which is the clean reading?

    SOme help please.

    The top one reads the gas levels for fuel control, it's the one after the cat that needs to be sleeved.
    The lamba cable should reach round the back of the gearbox to plumb in.

    So when i get my raceland mani, i will put the sensor that reads the gas for fuel control in the hole in the down pipep, and the sensor after the cat will be sleeved?

    Green one (top of old manifold) goes into whereever the lambda slot is in new manifold/exhaust section

    Blue one (bottom sensor after cat to read clean air) sleeved up
