[QUOTE="RX1Cobra, post: 15676620, member: 139306"] The rear O2 only tells the computer if you're cats are working. The car should run fun without them but will trip a CEL. Did you install an O/R pro chamber? If so that's why you're smelling gas... you don't have cats anymore. I'd guess the yellow is probably a coating that was inside the exhaust burning off. If you're running rich the coating/exhaust will be black. [/QUOTE]
