I took the car to a guy that builds custom exhaust. We drove it on the lift Saturday and he looked at it and said "I am going to decline this job". Had nothing to do with removing cats. He just said that he would not be able to tig weld the pipes and get it to seal correctly without completely removing it. So I called the next place and they were booked till November. I have another option that is about 45 minutes away, but I decided to say screw it and remove the primary and keep the secondary for now. it's a bolt-in deal and no hacking up the factory NPP.

How would removing primary cats cause false knock?
