Its weird. When you check the part # for the gaskets they are the same but the cats are completely different and specific to the 4.8iS. So they will bolt up out of the car and I guess it makes sense that they are routed the same but then turner states the 4.4 N62 SS headers and 4.8iS to not be compatible.
