    I have an 09 5.3 liter silverado I want put a set of long tube headers and a set of high flow cats my muffler guy said he did not want to mobe the cat locatoin becaus eof the sensors. Can I put the sensors anywhere as long as I have one before the cat and one after? Can I add lenght to the wires for the sensors and how much will long tube headers add in lenght cause I have play in the wires to move maybe four inches or so.
