No one was surprised by this.
By the way, my downpipe has been on for 500 miles now, Stage 1 EQT with no spacer/defouler. I still don't have a CEL.
I really feel good about the Gen2 cats being good to go. The Gen1 is hit or miss and normally needs one defouler, but I think fuel quality and driving habits (letting the car warm up before getting on it hard) also play a role in it.
