42DD downpipe and failed catalyst monitoring for emissions
Just wanted to see if anyone ran into a problem with the 42 draft designs 3" downpipe with their street catalytic converter on a 225QC. I can't pass emission tests because everything says ready except for my catalyst monitoring which reads "failed or incomplete"
I have no codes when i vag and no CEL so i'm wondering what the problem may be.
Thanks in advance for any ideas.

Your issue may be with the car/computer than the downpipe.
