Have just got the metal mule exhausts but am having a bit of an issue removing the lambda sensor shield thing from old exhaust. Cannot budge those bolts and am in danger of rounding them out. By the sounds of it I'll be having fun with the actual sensor aswell! I'm guessing that shield is important, did everyone else fit that part? If so did you have any trouble removing it?

boneman: I'm guessing you have a Power Commander for the o2 eliminator to work?
