True duals on 2006 FX4?
Someone told me that putting true duals on a 2006 FX4 should not be done because they have 4 catylitic converters and it messes with the sensors. I was also told it would void the warrenty. Is this true?

The rear two cats can be cut off but not the front two or you will get some thrown codes and other ****.
But the true duals themselves won't affect the cats.

Yeah they do. I have the 40 series on mine and I love it. I have a true dual system though so I think it is a little louder than running a single muffler.
