Hi,
Can anyone give me any pointers or help please?
I am swapping out my standard manifold on my 2009 4/4 with the Sigma engine to fit a Librands Sports manifold and hit 2 problems!
First I don't seem to be able to remove the old manifold / Cat, it doesn't want to come out?
No matter how I twist and turn it there just doesn't seem to be a route out of the wing hole / engine bay?
I really don't want to have to cut it in half......has anybody done this on here who might know the secret.
Secondly, my car has 2 O2 sensors, one before the Cat and one after the Cat.
The Librands only has a port which is before the Cat, is this going to be a problem?
I have had the Williams sports remap installed into the ECU but have no idea if that illiminates the need for the second O2 sensor?
Librands suggested that this manifold fits straight on.....I'm nolonger so sure

Has anyone been here and done this?
