That was precisely my question too. Just finished the install last night so I don't have any specific experience to share yet. However there are a number of posts that indicate since the secondary cats are not monitored you will not get any CELs. However, some have noted getting CELs but was determined to be a leaky connection at the slip joint just after the primary cat (rear O2 sensors would pick this leak up). With the leak fixed, CEL goes away.
We shall see.
