Not sure if my cats have any adverse issues but it has factory dual exhausts so has four cats. Can any of them be eliminated (straight pipes) or do they need to have replacments? Since it has four O2 sensors (two before the cats and two after) it is an interesting question. By the way, not sure if this is in the proper section.....Bobby
P.S. What is the proper way to find if the cats have issues (any form of blockages)???
